Latest revision as of 02:56, 28 October 2010
10/3/10
For Today:
- Run on a gel
- aoxa, aoxb next to the troubleshooting pcrs from today, specifically of the PCRS using Ompa-F and Aoxa/b-R since they are similar sizes
- Take out plates from incubator. Record observations
- Run colony PCRs on at least 20 colonies per construct (yes 20)
- Check which primers to use for colony pcr! We can likely use the primers we already have
- Run results on gel
Results: plated colonies from 10/2/10 (Mitesh & Rob):
Observed that HybB-ompA-Aox1(a/b) constructs were successfully transformed- strong colony growth and red colonies (strange- given that these were supposedly constructs without RFP). The color strongly suggests RFP. Red colony patterns show no consistent trends- some are densely red in the middle of the plate, others mainly around the edges- red intensity varied widely even on the same plate.
Colony PCR of HybB-ompA-Aox constructs
Picked colonies from plates of HybB-ompA-Aox-RFP and added to 25 ul of water each,10 colonies from Aox1a containing plates, and 10 from Aox1b containing plates:
HybB-ompA-Aox1a-RFP: 1.5 mL Tubes 1-10
HybB-ompA-Aox1b-RFP: 1.5 mL Tubes 11-20
Used 5 ul for PCR, and added 250 ul of LB media to the rest.
Colony PCRs (for each colony): (Rob, Mitesh & Scott)
5 uL of cells
25.5 uL H2O
10 uL GOTAQ 5X Reaction buffer
5 uL HybB-F forward primer
5 uL RFP-R reverse primer
1 uL dNTP 10 mM - (thawed & kept on ice)
0.5 uL polymerase enzyme, TAQ
Total Volume= 50 uL
Colony PCRs (for each colony):
5 uL of cells
25.5 uL H2O
10 uL GOTAQ 5X Reaction buffer
5 uL HybB-F forward primer
5 uL Aox1a or b-R reverse primer
1 uL dNTP 10 mM - (thawed & kept on ice)
0.5 uL polymerase enzyme, TAQ
Total Volume= 50 uL
Important: For the PCR tubes, the ones labeled 1,3,5,7,9 are treated with Aox1a reverse primer.
All the even number (2,4,6,...16,18,20) labeled have RFP-R reverse primer in them. And the tubes labeled 11,13,15,17,19 have Aox 1bR reverse primer in them.
PCR start time: 6 PM
For Monday:
- Check colony pcr on a gel
- calculate the predicted sizes and compare to gel results
- Continue with colony PCRS if more info is required
- Check triple ligations on gel

Protocols
1 % Gel to Check colony PCRs from 10/3/2010
Started at 9 am
Order:ladder:1-6|ladder|7-12|ladder|13-14
Important: For the PCR tubes, the ones labeled 1,3,5,7,9 are treated with Aox1a reverse primer.
All the even number (2,4,6,...16,18,20) labeled have RFP-R reverse primer in them. And the tubes labeled 11,13,15,17,19 have Aox 1bR reverse primer in them.
PCR start time: 6 PM
gel start at 10:34 am
Predicted Bands:
Hyb-F + RFP-R approx 2100-2200 bp
Hyb-F + Aoxa-R - approx 1500
Hyb-F + Aoxb-R approx 1500
Observations- 2200 bp band is seen, but other bands are also observed for the Hyb-F and RFP-R reactions
Suggestions:
- Troubleshoot by PCR sequencing the basic products (e.g. sequence just HybB in one tube, in the next, just OmpA; in the next, just AOX; in the next, just RFP). This will tell us whether each gene is actually present in the cells PCRed.
- Start over again entirely, from the very beginning, digesting each individual gene, ligating, transforming.
- Start using controls. When possible, include positive and negative controls.
- For example, when doing a double-ligation, for instance, perform experiment alongside designed to fail (e.g. lacking one of the ligation genes) for a negative control.
- To see if the plasmid pSB1A3 is causing our problems, transformed this plasmid alone directly into E. coli and plate.
- If pSB1A3 turns out to be the problem, can attempt to use a different plasmid backbone. We’ve researched and found plasmid pSB1C3 to have the desired characteristics, including lack of a promoter, beginning EcoRI and ending SpeI restriction sites.
Plan to go forward:
1. Transform “plain” plasmid pSB1A3 into E. coli today 4 OCT 2010. Check for RFP expression.
2. In tandem with step 3, troubleshoot by sequencing the basic gene products in the “bad” HybB-OmpA-AOX contsructs, looking specifically for each gene.
3. In tandem with step 2, re-do the entire construction process from the individual genes up.
4. Transform cells using new biobrick vectors, like psb1c3, and use those instead of psb1a3!
NOTE: Need to make more media plates!

10/6/2010
Goals
- The gel from 10/5/2010 of the troubleshooting pcrs, specifically the reaction of pSB1A3 with RFP-F and R, suggests that the vector used for ligation has RFP. We will use anothe rvector from biobrick
- We want to transform cells with the new biobrick vector today, miniprep the cells tomorrow morning, digest, and ligate to our hyb.ompa+aox that we have or are making now. Finish by friday is the goal.
- Sequence hyb-RFP (for bronze medal requirements)
- begin hyb-ompa-rfp building when primers come in
- I saw Richard’s sequence was for psb1c3, but we are using psb1a3; this may a primer and digests! Investigate!
- Sequence white colonies from the plates on 10/3/2010
- For today:
- Reconstitute new biobrick vector (psb1A7) COMPLETED
- Transform NB cells using new biobrick vector COMPLETED
- Check PCRs from 10/5/2010 on gel (tubes in yellow pcr box labeled 1-8 and dated 10.5) COMPLETED
- Make Amp plates
- Autoclave pipette tips
- This involves testing which tips are compatible with ours (we have lots of random tips)
Notes on Vector-
Here is an experience from another team concerning transcription of a product during an “off state”:
Our team (Davidson College) has used this vector in E. coli strain JM109 extensively. Clones are Amp resistant and are recovered in reasonable yields from mini preps. One drawback is that the vector has read-through transcription that comes into the cloned BioBrick part from both directions. This problem is a major one when an "off state" is critical for the control of a device. Parts without a promoter are expressed in this vector, regardless of orientation (see pSB1A7 Part Design for details). Reverse read-through might be from the Amp resistance gene. Forward read-through might be from a cryptic promoter, since no known genes in the backbone are in the plus orientation.
--Kahaynes 15:48, 23 October 2006 (EDT)
Alternative vectors:
- pSB1A7 (2010 Kit plate 3, 15G well, name BBa_K126000)
- Reasons:
- There are double terminators on either side of the multiple cloning site that block any read through or unwanted transcription from the plasmid promoters (plasmid promoters are involved in antibiotic production)
- Ampicillin resistance
- Already in kit
Protocols

make a new 1% gel in the orange pcr chamber (the chamber is the casting tray -- GENIUS!) (Christina)
See Protocols page for Preparing 1% Agarose Gels
PCR purifcation of psb1a3 pcr wiith RFP-F, RFP-R
See Protocols page for PCR Purifacation
Gel extraction of PCR from psb1a3 using primers RFP-F, RFP-R (Scott, Gita)
See Protocols page for Gel Extraction
Note: To elute DNA, added 30 μL water (pH 7.0 – 8.5), let the column stand for 1 min, and then centrifuged for 1 min.
RE Digest Recipe for RFP-F3R (that Debika did this yesterday)(Christian is doing the digest today)
12.5 uL H20
5uL 10X Promega Buffer B
6 uL RFP-F3R (167.4 ng/uL 10.6.2010)
5 uL BSA (1ug/uL, to a final conc of .1mg/ml)
0.75 uL SpeI
0.75 uL XmaI
Total=50 ul total
Run 3 hours in the heating block in our lab (37c, put water in the heating blocks)
Start 5pm
10/8/2010
Goals
- Nanospec the gel extract done on 10/7/2010 (of psb1a3 RFP-FR, 700 bp band)
- Run 4 uL of the gel extract on the gel and take picture (to prove psb1a3 has rfp!)
- Send off for sequencing:
- gel extract with RFP FR
- the mini prep of psb1a3 with RFP FR (mini prep from thursday)
- Repeat transformation of psb1a7!
- PCR purification of digest from (10/7/2010) of RFP F3R
See Protocols page for PCR Purification
- run on gel to check for 700 bp band
- if ok, then
- ligate to Hyb.ompa and psb1a3 or psb1a7 (which vector)?
Observations
The transformation of psb1a7 into NB did not work. We should check whether the strain is compatible with the plasmid.
The colonies from the transformation of psb1a3 directly from well into NB have turned slightly pink.
Liquid cultures of psb1a3 colonies from plates from 10.6.2010 appear brown with no pink. However, when we pelleted them for miniprep, the pellet was pink!
minprep of psb1a3 liq culture from palte from10.6.2010
Transformation of pSB1A7 in NB cells (with + control)
Megan suggested we use fresh NB cells (from Gaucher cells), use a positive control (known good plasmids)
2 reactions:
10 սL Nova Blue cells + 5 սL of mRFP from Gaucher Lab (labeled mRFP mini prep 3/11/09)
10 սL Nova Blue cells + 2սL of psb1a7 from well aliquot
See Protocols page for Heat Shock Transformation.

notes: elute in 30 uL!
Nanospec
- purified digest of RFP-F3R (labeled with 10.8.2010) = 18.1 ng/uL
- Gel extract of RFP FR (tube labeled 1, date 10.7.2010) = 84 ng/uL
- Gel extract of RFP FR (tube labeled 2, date 10.7.2010) = 91.3 ng/uL
- psb1a3 mini prep
- tube 1: 64 ng/uL
- tube 2 :56 ng/uL
Run on 1% gel
- Gel extractions from 10.7.2010 of psb1a3+ RFP-FR (2 tubes)
- purified, digested RFP-F3R from today, 10.8.2010
For tomorrow
- high priority
- pick colonies of psb1a7 (if succesful) and transfer to liquid culture
- tranform cells using psb1c3, since it is the vector we have to submit in.
- ligate RFP F3R to hyb.ompa and psb1a7 (likely have to be done sunday)
- autoclave more water
- Find some chloramphenicol since we have to submit parts in psb1c3 and it has chloramphenicol resistance
- low priority
- run pcr on psb1a3 minipreps today to check for rfp
10/9/2010
Goals
- Troubleshoot psb1a7, psb1a3
- List of wells, inserts, and sequences (http://partsregistry.org/assembly/libraries.cgi?id=31)
Notes
- Troubleshoot psb1a7
- does it have a cbbd toxic gene in it?
- No, it has an insert coding for a antibody chain, part: K126000
(http://partsregistry.org/wiki/index.php?title=Part:BBa_K126000) (http://partsregistry.org/assembly/plates.cgi?id=1259)
- can we digest (is it digested) and ligate it directly from the well to our parts?
- should we pcr it first?
- do we have a ccdb tolerant strain?
- Trobuleshoot psb1a3
- psb1a3 has RFP (http://partsregistry.org/partsdb/get_part.cgi?part=pSB1A3)
- BBa_J04450 = RFP
- tranform cells using psb1c3, since it is the vector we have to submit in.
- Have plasmid backbone from kit (Where is it?)
- Has RFP insert for in well Plate 1 - A3 (http://partsregistry.org/assembly/plates.cgi?id=1257)

For Tomorrow:
- PREFORM PCR on WHITE colonies to check for what is in them: triple ligation plates from Oct
- Ask Gaucher lab if they have 1) ccdb resistance strains 2) vector lacking promoters and have amp resistance 3) the three tubes of plasmid backbone from the standard iGem kit
- Need more Promega Buffer E
