Summary

Miniprep of Wintergreen registry parts.
Digestion and gel purification of Wintergreen parts.

MiniPrep

MiniPrep of Wintergreen parts from Registry (J45004 and J45700) following Qiagen MiniPrep protocol. MiniPrep three samples of each part.
- DNA concentrations:

         J45004-1: 59.1 ng/μL
         J45004-2: 72.9 ng/μL
         J45004-3: 88.1 ng/μL
 
         J45700-1: 146.7 ng/μL
         J45700-2: 187.4 ng/μL
         J45700-3: 175.5 ng/μL

Digestion with Enzymes

For J45004, we added: 9μL DNA, 1μL buffer, 1μL xbaI restriction enzyme (slow), and .5μL pstI restriction enzyme (fast).
For J45700, we added 5μL DNA, 4μL H2O, 1μL buffer, 1μL xbaI restriction enzyme (slow), and .5μL pstI restriction enzyme (fast).
We let mixtures sit for 30 minutes due to the use of xbaI restriction enzyme (slow). After the 30 minutes, we added 2.5μL dye to each mix.

Gel

We loaded 12.5μL of 1kb ladder to well 1 of the gel (numbered left to right). We then loaded 12.5μL of J45004-1, J45004-2, and J45004-3 to wells 2,3, and 4, respectively. We loaded J45700-1, J45700-2, J4500-3 in wells 5, 6, and 7, respectively (see images below for well locations).
Ran on 1% agarose gel.

Summary

Trouble with ligations
Troubleshooting different enzymes showed a non-functional XbaI
Digest of parts using slow XbaI

We began this week trying to ligate the pENTCUP2 promoter, NosT terminator, and NosT terminator plus stop codon into the V0120 vector. We ran into several problems during this process.

We had previously digested the three inserts as well as the promoter with XbaI and PstI fast digest enzymes, ligated, and transformed the ligated vectors into e. coli. Unfortunately, we did not find any colonies of cells after over 14 hours of incubation. Furthermore, on Friday June 18th, after digesting all three inserts and vector and running them on a gel, we did not see any NosT + stop DNA. Therefore, on Monday June 21, we began by digesting more NosT + stop and V0120 vector with xba1 and pstI fast digestive enzymes. The gel showed DNA length to be consistent with the given parts. (See gel below)

Gel Lanes (both inserts and vector were digested with xbaI/pstI): 1. 1kb plus ladder. 2. NosT + stop terminator. 3. V0120 digested.

Upon gel extraction and gel purification, we ligated the inserts into the vectors with a 2:1 insert to vector ratio (previously we had been using a 4:1 insert to vector ratio). We then transformed the plasmids into e.coli and plated; no colony growth was seen the next morning.

We used Team Vector's R3 ligation (they have successfully ligated and transformed) as a positive control. However, the bacteria containing the ligated plasmids were plated on Ampicillin plates, which turned out to be the wrong resistance.

Troubleshooting

In order to get a better understanding of the problem with our ligation, we ran a diagnostic gel with the V0120 backbone and vectors B15 and B21.

We concluded from the gel that xba1 is the problem in our ligation step. The pattern of bands in the v0120 xba1/pstI digest along with the v0120 xba1 digest illustrate that xba1 is not cutting correctly.

We began a slow enzyme xba1/pstI digest on Friday, but the gel was run in mismatching buffers (TAE and TBE).

Valencene Digestion of PCR products aimed to isolate valencene gene showed very short length on gel. These are not the correct size and are most likely primer dimers. PCR products were digested with EcoRI/SpeI. 5 μL of each sample was digested with pstI to be sure that the pstI site was in the sequence of DNA.

Lane 1	1KB Plus Ladder
Lane 2	pENTCUP2
Lane 3	NOSt
Lane 4	NOSt+STOP
Lane 5	B15 digested
Lane 6	B15 undigested

The undigested B15 in lane 6 appears as two bands on account of supercoiling of the B15 plasmid.
Bands in lanes 2 - 5 were cut out and purified using a Qiagen Gel Purification kit
- The gel purification was done with 300 μL Buffer PB and 400 μL Buffer QG

Nanodrop Specs
Name	Concentration (ng/μL)
pENTCUP2	16.5
NOSt	10.2
NOSt+STOP	0.4
B15 (backbone vector)	10.9

Note the very low concentration of NOSt+STOP. It is uncertain as to what caused such a concentration, but transformation proceeded anyways with max volume
The ligation reactions were preformed at at 2:1 (insert to backbone) Molar Ratio
- The sole exception being the NOSt+STOP ligation, in which the lack of product forced us to use 1.8 ng DNA

Ligation reactions were preformed as per the Silver Lab ligation protocol (with the differences in concentration and ratio made as per the table above).
Transformations to E. Coli were preformed as per the Silver lab transformation protocol with ampicillin plates.
Plates were left overnight.

Digestion, Ligation and Transformation of Miraculin and Brazzein into BioBrick.

Results of ligation and transformation of The Big Three (pENTCUP2, NosT, NosT + stop) with B15 backbone into E.coli

A few colonies were found on the pENTCUP2 + Backbone plate, NosT + stop and backbone plate, and b15 backbone control plate. Colonies were picked from the plates and placed in 3ml of LB and agarose in a culture tube. The tubes were placed in the 37°C shaker for 8 hours. 2 mL of LB+AMP was added to the cultures, bring the total volume to 5 mL of LB+AMP. Cultures were left to shake overnight.

Summary

Confirmation gels of NOSt+STOP part and reverse transcriptase reaction.
- NOSt+STOP ligation was confirmed.
- RT reaction of Valencia RNA failed.

NosT + stop and v0120 We ran an xba/pstI fast enzyme digest on our miniprepped NosT + stop and v0120 plasmid. The gel was consistent with a successful ligation. (See lanes 7-10 in gel image below).

Valencene After running a reverse transcriptase reaction on our RNA extraction, we ran PCR on the cDNA with Valencene specific primers. The gel did not show the proper fragment length of the Valencene gene. Instead, it appears primer dimers formed again. (See lanes 2-5)

- It appears that the digestion of Mira+YFP C2 (lane 7) did not work properly. This could have been the result of choosing a bacterial colony that was the result of contamination, or from simply an error in the digestion step.

Summary

Ligated Strep tagged flavor proteins with stop codon

Miraculin N/Brazzein C StrepII & Stop

We ran a confirmation digest on the miniprepped Miraculin N StrepII & Stop and the Brazzein C StrepII & Stop. We digested the samples with XbaI/PstI. We should have used NotI/SpeI in this digest if we planned on inserting into V24 pETDUET vector.
- We digested 558 ng of Mira N1, 516 ng Mira N2, 540 ng Brazz C1, and 551 ng Brazz C2 in 20 μL digestion reactions.

We also ran undigested samples of all four to help determine why the other ligations (Brazz N and Mira C) did not work.
- We ran 279 ng of Mira N1, 258 ng Mira N2, 270 ng of Brazz C1, and 275.5 ng Brazz C2.

Backbone: 3.2 kb; Insert: 1.1 kb

Analysis
Both the backbone and the insert in lane 1 look like the correct length (3.2 and 1.1 kb respectively). Lane two consists of a backbone of the correct length, but the insert appears to be ~1.5 kb, too long for the J45004 BioBrick part. Lane 3 appears undigested; we are uncertain as to why.

Transformation of Mira/Brazz StrepII constucts into E45

100-200 ng of construct DNA was transformed with 15μL of E45 expression E. Coli; transformation procedure was followed; transformed cells were plated on LB+AMP and left to grow O/N

Transformations: Mira N1 Mira N2 Mira C1 Mira C2 Brazz N1 Brazz N2 Brazz C1 Brazz C2

08-26-2010 [top]

Overnight cultures of E. Coli transformed with StrepII-tagged Miraculin and Brazzein under an inducible promoter were back-diluted to an optical-density of 0.1.
Cultures were allowed to reach an O/D of 0.5
IPTG was added to a final concentration of 100μM
After 3 hours, cultures were spun down, the supernatant removed and the bacteria frozen overnight at -80°C

08-27-2010 [top]

The IPTG induced bacteria were lysed with B-PER II lysis reagent via standard protocols
Total lysate was run on a 4-12% Bis-Tris NuPAGE gel and transferred to a PVDF membrane
Blocking buffer added, gel was left at 4°C overnight

08-28-2010 [top]

Blot was exposed to a StrepII-tag Antibody, HRP conjugate from Novagen
Left overnight at 4°C

08-29-2010 [top]

Blot was developed and imaged.

Strong expression of Brazzein was seen, however Miraculin was not. Despite this low expression, this could very well be a bacteria-specific reduction.
