We did initial PCR/PCA today!

For part sbb1216:

Obtained and made a 10 micro molar solution of oligos ca998/osbb1333R and osbb1216F/g00101 for PCR.

Set up two solutions for PCR:

This one I call A in construction file:

24uL ddH2O

3.3uL 10x Expand Buffer "2"

3.3uL dNTPs (2mM in each)

1uL ca998, 10uM

1uL osbb1333R, 10uM

0.5uL Expand polymerase "1"

0.5uL pBca9145-jtk2768

And...

This one is B:

24uL ddH2O

3.3uL 10x Expand Buffer "2"

3.3uL dNTPs (2mM in each)

1uL osbb1216F, 10uM

1uL g00101, 10uM

0.5uL Expand polymerase "1"

0.5uL pBjk2741-jtk3346

For part sbb1205

I set up a solution based on the PCA protocol on open wet ware.

38 uL ddH2O

5 ul 10x expand buffer

5 ul 2mM dNTPs

1 ul oligo mixture (100uM total, mixture of oligos after combination of 100uM stocks)

0.75 ul Expand polymerase

Ran two lanes on agarose gel for gel purification of products A and B from last time. Extracted the product A from the gel. The lane for B was very faint so I have decided to redo the gel one more time before considering whether it was a mistake in an earlier step :(

Created the PCA solution for creation of pca2.

For next time: I will rerun the gels (PCR A&B with loading buffer), extract Create the digests for the part and template and use thermocycler (time for ligation ?)

Possibly with time remaining, I will set up the pcr reaction with A+B

For the sbb1216 part, I ran the two PCR products from last week on the agarose gel for gel purification:

PCR ca998/osbb1333R on pBca9145-jtk2768 (A)

PCR osbb1216F/g00101 on pBjk2741-jtk3346 (B)

Obtained alright results, can be seen on the gel two lanes 8 and 9.

Cut out the bands and did the rest of the gel purification for both A and B.

For the Leucine Zipper part (sbb1205):

I had the pca2 product from last week, which I ran on gel for analysis (lane 4 ?) looks alright.

Did a cleanup of the pca2 product (did the protocol for regular zymo cleanup which I think might have been better to use the small frag

cleanup given the size of the pca2) and proceeded to do the digest of pca2 with NheI/BamHI following the protocol for EcoRI/BamHI

Digest of Wobble Products for the size considerations. Kept the digest on 37 degrees on the thermocycler for ~1 hour. Finally did a

zymo small fragment cleanup this time.

Set up the A+B PCR with parts ca998/g00101 for my sbb1216 part

Same PCR protocol as before but there are two templates A and B from last tuesday that is supposed to anneal at their complementary

region as part of the Soeing PCR process

Also attempted a transformation but underestimated the time requirement

Ligated the PCA2 digest with NheI/BamHI with the Bca1834 vector digest NheI/BamHI.

Allowed the Ligate product to incubate for 30 minutes on benchtop.

Went through the protocol for transformation with 200 micro liters of cells.

• • Last step modification: (not sure how it will affect the cells ability to have grown) only incubated the cells with ligate for around

35 minutes versus 1 hour after heat shock.

Zach picked the colonies over the weekend and had them growing in tubes when we arrived today. He picked 4 colonies (white, the red

colonies indicates failure of transformation and there were some red colonies). Only one of my colonies out of 4 grew. I did miniprep

procedure to isolate the plasmid DNA from this colony of cells using the protocol listed in open wet ware. The extracted DNA has

been saved in a tube (eluted with water to a total volume of 50 micro liter). Now I need to digest and run an analytical gel before

deciding whether or not to sequence.

I also picked three more colonies from the plate to grow overnight to see if I have any success growing more, see if more of them

transformed.

For the other part I am working on (sbb1216) I got back the pcr product for the A+B pcr reaction with end oligos. Ran it on gel,

results will determine whether I can digest, ligate, etc.
