* DTLs of amiRNA insert were unsuccessful. Yesterday we concluded this was because turbo cells + amp resistance don't grow on YEB media (we were out of LB+amp media). Today we must adopt a new hypothesis as 0/16 colonies grew on LB+amp media. Working theory is that the backbone digestions pictured below have the digested backbone and inserts as the two bands (top to bottom) instead of the undigested & digested backbone (in hindsight, I was trying to ligate into YFP*2, the original insert of B21). The confusion arose from the 1kb ladder, which at first appeared to match another ladder far better than 1kb (see Thursday's entry or thereabouts). This, combined with the fact that the 1kb ladder was hand-labeled, led me to suspect that it was in fact the other ladder (pR322 as pictured [http://openwetware.org/wiki/Image:Ladders.jpg here]). This, in turn, supported the (theorized incorrect) conclusion that the top & bottom bands [http://openwetware.org/wiki/Image:Bbcut1.jpg here] and [http://openwetware.org/wiki/Image:Bbcut2.jpg here]  were undigested & digested backbone, respectively, and that the insert had diffused. I've DTL'd again, this time using the upper band (which didn't separate into digested & undigested bands after running for 30m on a .7% agarose gel) for ligation. We'll see on Monday how it went.

I've DTL'd again, this time using the upper band (which didn't separate into digested & undigested bands after running for 30m on a .7% agarose gel) for ligation. We'll see on Monday how it went.

Progress

  1. Identified allergens in arabidopsis, strawberries,tomatoes, and carrots and created primers for amplifying out these allergens (see primers and sequences)]
  2. Extracted cDNA (rna extraction followed by rt-pcr) from strawberries and tried to PCR out our strawberry allergen (Fra a 1), but were unble ato do so
  3. Looked to find introns ~ 800 bp to use to create our hairpins since it was difficult to acquire pHannibal vector w/ the pdk intron

Future Directions

  1. Look towards ordering amiRNA for silencing
  2. Waiting on arabidopsis plants to grow to extract genomic DNA (mon)
  3. Look to find introns to use in creation of hairpin DNA
  4. Cloning (digesting/ligating our sense/antisense/intron sequences necessary for hairpin creation into one vector to create biobricks)

Today, we did not do work with hpRNA and focused our efforts on amiRNA. We obtained undigested V0120 with a death gene insert from Team Flavor, and we have inserts from previous PCR reactions that all need to be digested and ligated into V0120.

Procedures:

  1. Digestion of Allergen Panel and V0120 with Xba and Pst
  2. Ligation of Allergen inserts into Vector Backbone
  3. Transformation of E. Coli

Results

Digestion of allergens yielded the following concentrations:

Bet: 58.2 ng/uL; LTP (.5): 38.6 ng/uL; GFP (.5): 43.9 ng/uL; GFP: 29.1 ng/uL; LTP: 60.4 ng/uL; Backbone: 20.2 ng/uL

06-30-2010 [top]


  • Checked for transformants. No viable colonies except for Bet, but those two colonies could be just background.
    • Grew up 2 tubes for minipreps at ~10am (Should be ready ~ 4 pm)
  • Miniprepped w/ concetnrations of ~ 80 ng/uL and 108 ng/uL
  • Redid ligations and transformations (plated ~ 12 pm)
    • Bet, LTP, GFP, LTP .5, GFP .5, Negative Control (just V0120 backbone)
  • Transformed ligations into turbo cells and let it sit outside rather than in 37
  • PCR of PAL3 and PME2 introns from arabidopsis genomic DNA

07-01-10 [top]

  • Ligations for full amiRNA and V0120 (w/o death gene)

note: .5 denotes multistep pcr reaction from yesterday in which .5 uL of part 3 of gfp/ltp were use in one of the three in one assemblies of parts 1,2,3 w/ primers A&B

Ligation Reactions

  • Used 50 ng of backbone and 150 ng of insert (ratio of insert to vector ~.14
  • Did 1:10 dilutions for the digested inserts


  • PCR of PME3 and PAL2
    • saw no bands from last night's pcr so we re ran it again.

Annealing Temp: 69C Extension Time: 30 sec

2 PCR reactions (PME & PAL)

    • Concentrations: PME: 250 ng/uL PAL: 134 ng/uL
  • gel: lane 1:ladder; lane 2: Pal3; lane 3: Pme 2; lane 4: ladder

  • Ligation of Antisense/sense allergens into V0120 (lacking death gene)
    • Used 34 ng of backbone and 10 ng of insert (ratio of insert to vector ~.09375)

07-02-2010 [top]

  • Check on sequences for Bet
  • Digest Pme3 and Pal 2 introns/Ligate w/ V0120/Transform
    • PCR purified digests
      • Concentrations: Pme (ranges from 20-36 ng/uL); Pal (ranges from 20 to 28 ng/uL)
    • Ran backbone on gel and gel purified (Concentration: 3.1 ng/uL)
  • Ligations of Pme/Pal w/ V0120
    • bbone 2 was potentially contaminated at a higher concentration 96.1 ng/uL
  • Check on transformations of amiRNA (5 transformations) and antisense/sense allergens (8 transformations)
    • There were colonies from the amiRNA transformations
      • We grew up 24 colonies (3 for each GFP, GFP .5, LTP, LTP .5, BET) ~ 10 am to be ready ~3 pm for minipreps)
      • The other 8 transformations did not show any colonies--we put it back in to see if we would get colonies (only 100 uL instead of 200 uL was plated)
      • To do: Grow up colonies to miniprep, run on gel, sequence
  • pHannibal and pKannibal arrived today (hannibal is amp resistant and kannibal is kan resistant)
    • We transformed these plasmids

07-03-2010 [top]

Team Allergy
Today, we isolated plasmid that contained antisense and sense sequences of the allergen panel and introns PME and PAL that we grew last week.

Procedures
For amiRNA

  1. Nanodrop of miniprepped amiRNA plasmids
  2. Diagnostic digest of amiRNA plasmids
  3. E Gel of digested amiRNA
  4. Send plasmids to Genewiz for sequencing

For ihpRNA

  1. Miniprep of plasmids containing introns for hpRNA
  2. Nanodrop of miniprepped intron plasmids
  3. Miniprep of plasmids containing Allergen Panel sense and antisense
  4. Nanodrop of minipreped allergen plasmids
  5. Diagnostic Digest of introns and allergens
  6. E Gel of digested parts
  7. Extract pKannibal and pHannibal vectors and transform into E. coli
  8. PCR of the PDK intron in pKannibal and pHannibal

Miniprep of turbo bacteria for plasmids containing sequences for amiRNA

Should obtain plasmids containing the complete sequence for amiRNA. The resulting concentration should be relatively high (<100ng/μL) because all growing bacteria would have the plasmids inside.

Nanodrop of miniprepped amiRNA plasmids

We used 2μL of DNA per nanodrop.

Concentrations in ng/μL
Sample # --> One Two Three
GFP 134.4167.6 207.2
GFP 0.5 163.3 106.9 230.9
LTP 134.0 127.8 165.5
LTP 0.5 158.5 137.2 113.5
Bet 129.4 78.9 124.4

Diagnostic digest of amiRNA plasmids
Digested 200~500ng of plasmids with EcoR1 and Spe1. We will then run the digested vectors on an E Gel and look for DNA that is the length of the insert. If such DNA appears on the gel, then we will send it off to be sequenced.

E Gel of digested amiRNA

We had to run 21 samples, so we used two gels. The orders were:

Gel #1

  1. 1kb Ladder
  2. GFP 1
  3. GFP 2
  4. GFP3
  5. GFP 0.5 1
  6. GFP 0.5 2
  7. GFP 0.5 3
  8. LTP 1
  9. LTP 2
  10. LTP 3
  11. LTP 0.5 1 no visible band for neither plasmid nor insert
  12. LTP 0.5 2

Gel #2

  1. 1kb Ladder
  2. LTP 0.5 3
  3. Bet 1
  4. Bet 2
  5. Bet 3
  6. Neg Control for hpRNA (digested with Xba and Pst, and ligated without new inserts) no visible insert band
  7. Neg Control for intron (digested with Eco and Spe, and ligated without new inserts)
  8. PME Good no visible insert band
  9. PME Dubious no visible insert band
  10. PAL Good colony 1 no visible insert band
  11. PAL Good colony 2
  12. 1kb Ladder


Miniprep of plasmids containing introns for hpRNA
Nanodrop of miniprepped intron plasmids

We used 2μL of DNA per nanodrop.

  2. Nanodrop of minipreped allergen plasmids
  3. Diagnostic Digest of introns and allergens
  4. E Gel

phannibal and pkannibal Extracted vectors from a piece of paper per instructions. Transformed vectors into E. coli. Miniprep and PCR to extract PDK intron.

  • pcr to get out pdk intron

07-07-2010 [top]

Yesterday, we ended by transforming pKannabil and pHannibal into E. coli and running a diagnostic digest of digested allergen panel. Yesterday's plates did not grow, and the diagnostic digest did not have good results.

  • Today, we will be redoing diagnostic digests of the allergen panel plasmids to see if we can see our desired bands (300 bp and 3200) and re-transforming pKannabil and pHannibal.
    • If the digested allergen panel runs correctly on a gel, then we will send the plasmids off for sequencing.
    • If nothing gel does not run correctly, then we will go back to re-digest V0120 with a death gene insert instead of YFP and ligate allergen inserts, transform, miniprep, and see if we get the correct insert. **If some run correctly and some did not, we will collect more samples from our culture plates for the allergens that did not work and redo the digests until we find a sample with the correct plasmid.
  • If the pKannabil and pHannibal plates grow, then we will miniprep to purify the plasmids containing the PDK intron, PCR the intron, and purify the intron.
  • Today, we are also running the PDK intron obtained yesterday to see if it is the correct length.

First thing tomorrow, we will culture E. coli containing plasmids for our allergen panel to obtain more plasmids.

Procedures

For pKannabil and pHannibal:

  1. Electronic Gel Electrophoresis of PDK introns (from PCR reaction yesterday, PCR off DNA from the eluted vectors)
  2. Re-grow E. coli containing pKannabil and pHannibal plasmids
  3. Culture colonies
  4. Miniprep colonies
  5. PCR for PDK intron
  6. Diagnostic Gel to check for correct length
  7. Repeat PCR of PDK intron using different Tm (gradient pcr)

For Allergen panel

  1. Digest of Plasmids containing allergen inserts
  2. Diagnostic Gel
  3. Collect additional samples for allergens that did not work

Results

Transformation of pHannibal pKannibal
This transformation we performed slightly differently from the one yesterday. This protocol is nicknamed the "quick and dirty transform." The transformation we started yesterday of pH and pK didn't work (no growth on either plate).

Quick and Dirty Transform:

  1. Mix
    1. 2ul 10x {pHannibal, pKannibal}
    2. 20ul Turbo E. Coli
    3. 220ul SOC Broth
  2. Plate on {LB+(pHannibal->LB+Amp, pKannibal->LB+Kan), LB} Agar, grow

PCR of PDK intron

  • PCR of PME3 and PAL2
    • saw no bands from last night's pcr so we re ran it

Annealing Temp: 69C Extension Time: 30 sec


Concentrations: PDK:46.5 ng/uL & 36.5 ng/uL Didn't work. Our theory is that the Tm we used (the one IDT sent us) was too high. IDT assumes that the entire primer is going to anneal to a strand of DNA when they calculate their Tm, but since half of our primer won't anneal (the half that doesn't anneal was used to prepend/postpend the biobrick sequences) the Tm IDT calculates will be too high. Here are more correct calculations from Primer3:

OLIGO            start  len      tm     gc%   any    3' seq 

LEFT PRIMER       4229   20   51.11   30.00  8.00  3.00 CCAATTGGTAAGGAAATAAT
RIGHT PRIMER      5021   20   61.95   45.00  6.00  0.00 TTCGAACCCAATTTCCCAAC


See Gel Image Below: ladder, lane 3 and 5 are pdk intron

Lanes:
3. pdk intron
5. pdk intron


Gradient PCR

Annealing Temps: 50,55,60,65

Extension Time: 30 sec

Ran 8 reactions, for samples from lane 3 and 5 for each of the four temperatures.

Concentrations: PDK: 12.7 ng/uL

Remaining steps

  1. Culture colonies
  2. Miniprep colonies
  3. PCR for PDK intron
  4. Diagnostic Gel to check for correct length
  5. Repeat PCR of PDK intron using different Tm.


Digest of Plasmids containing allergen inserts
Digested with Xba and Pst using Fast Fermentas digest protocol


Out of the 24 lanes, 6 were successful. Of the 8 allergens, 3 were successful. Samples of LTP sense, Betv1 sense, and Ger sense had one band at around 3kbps and one band at 300bps. The other genes had one band at 3kbps and additional longer bands on the scale of twice or three times the length of the plasmid.

For the allergens that did not work, we will go back to our bacteria plates and sample 5 additional colonies for each allergen, grow up 10 mL overnight cultures, and miniprep so that we can redo the diagnostic digest. We are hoping that a larger sample size would allow us to find colonies with the correct plasmid.

Remaining Steps

  1. Collect additional samples for allergens that did not work
  2. Culture them
  3. Miniprep
  4. Diagnostic Digest and Gel

Today, we received sequences for the allergen , intron, and amiRNA inserts. Since 4 of the 8 allergen inserts were not correctly done (and were not set for sequencing) and we want to repeat the inserts that DID work, we will redo ligations for the entire panel.

Procedures

  1. Check Sequencing Results
  2. Redo Ligations for allergen Panel

Sequencing Results

  • amiRNA
    • GFP #1 & GFP.5 #3 worked
    • Bet,LTP did not work
  • intron
    • Pal(#2) matched
  • ihpRNA
    • LTP Sense 1,2,3 and Ger Sense 1 matched
    • Bet sense did not match

Full report (annotated sequences): File:Report.zip

Redo Ligations w/ phosphatized backbone for entire allergen panel,

PME did not grow, we will not use it since we have good PDK and PAL introns.

PAL and PDK will be digested and inserted into a plasmid containing a sense strand of an allergen.

Add PDK to amiRNA vectors if sequences match up

Today, we did minipreps of intron and backbone. Would have also done minipreps of intron plus allergen part but none of those colonies grew.

We also miniprepped Betv1.2 Sense, Betv1.1 Sense, Bet 1.2 Antisense, and Ger Sense of the plates that we grew on Monday. The rest of the allergen panel did not grow properly. What colonies that WERE on the plate grew probably because AMP was not spread properly on the plate. We deduced this because those colonies could not grow in liquid media. We are waiting on more LB amp plates so that we can redo ligations, which is probably the reason for our lack of colonies.

We will do diagnostic digests of all miniprepped DNA.

Today, we plated the transformations that we did yesterday. We are also expecting sequences for amiRNA that we ordered yesterday.

Procedures

  1. Plating transformants
  2. Check sequences

Results

Plating Transformations One plate of each allergen S and A and the introns PAL and PME. All but BetS and PME had colonies

Sequencing Results for amiRNA

Not one matched the sequences that we wanted. The customization sequences that we wanted (our miRNA sequence+ a little bit of RS300) were not present in all of the LTP and Bet sequences sent in. Even the Biobrick ends were not present in the sequences except for GFP, from our earlier sequencing order.

What could have gone wrong? We suspect that the RS300 vector that was given to use already contains an interference sequence. The sequence that we used to design our primers are based on an RS300 vector without any inserted interference sequence. Christina has already sent an email to the lab that gave us the RS300 asking if the RS300 contains any interference, possibly GFP. That would explain our results.

It is possible that we will have to go back and redo PCR ~ transformation. These results are all still from the first time that we tried making amiRNA parts, just different colonies.

"c1" and "c2" are the customization (mutagenesis) sites corresponding to the capitalized portions of the primers suggested by the WMD3 tool. 
"c1" corresponds to the capitalized region of what WMD3 calls primer3 and to the reverse compliment of the capitalized region of primer4. 
Similarly, "c2" corresponds to the capitalized region of primer1 and the reverse complement of the capitalized region of primer2. 
For instance, WMD3 gives us the following when asked to design primers for the BET sequence:
primer1:	gaTTGGTTATATATATCGCACCTtctctcttttgtattcc
primer2:	gaAGGTGCGATATATATAACCAAtcaaagagaatcaatga
primer3:	gaAGATGCGATATATTTAACCATtcacaggtcgtgatatg

Today, we are expecting our sequencing results from Genewiz. Once those arrive, we will check the sequences for both the primers and the correct allergen sequence (around 300bps). If the sequences are correct, we will go back to our plasmids and cut the intron out of the plasmid and digest the plasmids containing the sense strands with S, P.

Procedures

  1. Check Sequencing Results
  2. Digest Intron with X, P
  3. Digest Plasmids with Sense with S,P
  4. Gel Electrophoresis of Digested Plasmids (both Intron and Sense)
  5. Gel Extraction and Purification of Intron and Antisense
  6. PCR purification of Sense + Bbone

Results Sequencing Results

  • Ger S (all 3 samples had correct sequence)
  • Ger A (all 2 samples had correct sequence)
  • Bet 2S (#3 did not work. #2 had correct sequence)
  • Bet 2A (all 3 samples had correct sequence)
  • LTP S (all 3 samples had correct sequence)
  • LTP A (all 2 samples had correct sequence)
  • Pal (#3 did not contain plasmids. #1 and #2 had correct sequence)
  • PME and Bet v1.1 S did not grow up from the plates, so they were not included in sequencing.


Digest Intron with X, P Fast Fermentas protocol was used.

Digest Plasmids with S, P Fast Fermentas protocol was used.

Gel electrophoresis of Digested Plasmids We PCR purified the products of the digestion (unnecessarily), losing some DNA. Elution was done with 50μL of EB. Tomorrow, we will run the purified PCR products on a gel and Gel Extract and Purify.

07-23-2010 [top]

Today, we will create our very first biobrick vector with both the sense and intron parts. We will use parts digested yesterday, purify them, and ligate them together.

Procedures

  1. Gel Electrophoresis of Intron and Antisense
  2. Gel purification of Intron and Antisense inserts
  3. Ligation of Intron insert and Sense + V0120
  4. Transform and plate

Results
Gel Electrophoresis

Antisense cut w X P.jpg

All the Antisense and intron lanes showed, though the last lane (PAL) was faint.

Gel Purification Nanodrop of gel purification had concentrations of:

  • LTP: 1.8, 2.9
  • Bet v1.1: 6.0, 3.2
  • Bet v1.2: 1.8, 0.5, 1.3
  • Ger 3: 0.8, -0.5
  • Pal: 6.7, 0.7

There is some cause for concern for the lower concentrations, since these small numbers are outside of the range of accuracy.

Ligation of intron insert into Sense + V0120 PME was ligated into all backbones containing sense parts of the allergen panel (8 rxns), followed by PAL ligation into the same backbones. We plated two of each PAL ligation in case that there might be some increased chances of finding growth on plates if more than one plate is done for each ligation. We will check for colonies Saturday.

07-26-2010 [top]

Procedures

Last week, we finished ligation together Sense and Intron parts of the hpRNA and transformed them into E. coli. This week, we will extract the plasmids, add in the antisense part, and transform.

Procedures today...

  1. Culture colonies (done over the weekend)
  2. Miniprep of V0120 sense + PDK, PAL intron parts
  3. Diagnostic Digest

We also need to check which parts of the sequence on the team page corresponds to the sense/antisense parts of the gene. There may have been mistakes in the past.

Results Culture We cultured 38 colonies. All grew but one LTP+PAL and Ger+Pal grew. We labeled the cultures 1- 38 for simplicity sake.

Diagnostic Digest

We digested the vectors with Spe and Pst1 and ligate with antisense parts (already digested and gel purified). We ran them on the E Gel too long so the lanes do not show anything conclusive, other than that there is digested DNA in the bottom half.

Result: 2-assembly digest.jpg

Sequence review clarified which parts of the sequences on the team page corresponded to sense/antisense.

<a name="07-27-2010" class="date">07-27-2010</a> [<a class="top" href="#notebook">top</a>]

Procedures

Yesterday, we tried to run a diagnostic digest of the Sense + Intron hpRNA. The gel did not work properly, so we are redoing the gel today. We'll also go ahead and ligate antisense parts into all 38 minipreps that we HOPE contains correct Sense + Intron. Once the gel finishes running, we can go back and dispose of the ligations today that do not contain the correct S+I parts.

Today, we are also going to redo the ligation of Sense + Intron for PDK colonies because the gel that we are redoing today suggests that no PDK worked from last week's ligation.

Results

Diagnostic Digest

38 digests of the sense+intron miniprepped plasmid DNA. The digest was done with Slow Digest Eco and Pst

From the digest, we can see that two LTPS+Pal worked (9,11), 3 Ger3S+Pal worked (36-38), 4 Bet2S+Pal Worked (25-28)

Lanes are: 1-6: LTP + PDK (3200 & 1200);

Rerun of the lanes that were ligations of PDK + sense because they did not show on the gel above. We feel that there might be a chance that if the Sense+PDK assembly did not work, the 300bp evidence ran off the first gel. This second gel shows that most of the PDK+sense did NOT work. Only three worked -- minipreps 16, 30, and 31.

(9 c1, 25 c2, 36 c1 have a 540 and 3200 band as opposed to a 840 and 3200 band--prbly b/c sense+intron is there but antisense was not ligated in). All intron+sense parts except for LTPS+PDK appear to have 300 bands as well indicating that PDK was not ligated in.

(a small mix up with two of the lids was made and its possible that LTPS+PDK (w/ an 840 and 3200 band is actually the complete Bet2 part so we're sending this in for sequening anyway).

  • DTLs of amiRNA insert were unsuccessful. Yesterday we concluded this was because turbo cells + amp resistance don't grow on YEB media (we were out of LB+amp media). Today we must adopt a new hypothesis as 0/16 colonies grew on LB+amp media. Working theory is that the backbone digestions pictured below have the digested backbone and inserts as the two bands (top to bottom) instead of the undigested & digested backbone (in hindsight, I was trying to ligate into YFP*2, the original insert of B21). The confusion arose from the 1kb ladder, which at first appeared to match another ladder far better than 1kb (see Thursday's entry or thereabouts). This, combined with the fact that the 1kb ladder was hand-labeled, led me to suspect that it was in fact the other ladder (pR322 as pictured [http://openwetware.org/wiki/Image:Ladders.jpg here]). This, in turn, supported the (theorized incorrect) conclusion that the top & bottom bands [http://openwetware.org/wiki/Image:Bbcut1.jpg here] and [http://openwetware.org/wiki/Image:Bbcut2.jpg here] were undigested & digested backbone, respectively, and that the insert had diffused. I've DTL'd again, this time using the upper band (which didn't separate into digested & undigested bands after running for 30m on a .7% agarose gel) for ligation. We'll see on Monday how it went.
  • New Plan of action:
  1. Redigest V9/V10 (three digests of each backbone to use more DNA in ligations)
  2. Grew up V9/V10+ ihpRNA colonies
  3. Re pcrd amiRNA and digested to ligate into V9/V10
  4. Catalog parts to be ready for the registry

ihpRNA

  • Only 2 colonies grew up (V10 9 (37c1) and V10 12 B(38 c2)) ger ihprna constructs
    • growing up colonies again in 5 mL cultures w/less antibiotic (50 ng/uL of kan)
    • concentrations: V10_9: 21.4 ng/uL V10_12B: 16.9 ng/uL
  • Diagnostic Digest (Should see ~ 7 kb band and 840 band)

Diagnostic Digest Ger ihpRNA into V10

  • Did not see exepcted bands (waiting on cultures grown up today to miniprep and hopefully transform into agrobacterium tommorow)

amiRNA

  • Ligated into V9/V10 and transformed

  • Minipreps of (V95, V91, V99, V99b, V1011, V107B, V1012, V109b)
    • Concentrations (20-60 ng/uL range)
  • Diagnostic Digest (should see ~ 7 kb and 840 bp)
