Tube 1-6 containing 5uL pZA21 plasmid template and 3uL of each primers for amplification of the backbone. Tube 7-10; 1uL g-Block from previous purification and 3uL of each Sec signal primers. Tube 11-14 containing same amount of g-Block and primers but now replaced with the TAT2 signal primers. Tube 15-18; 5uL GFP SF plasmid template and 3uL of each primers for GFP SF TAT.

All tube with less than 5uL template DNA was filled with MQ until final volume of 11uL(5+3+3).

First half of the samples where run on PCR with x7-polymerase and the second half where run with PHUSION-polymerase, with the exception of the g-Block where all reactions where run with PHUSION. This gives following setup:

Inconsistent results from the first PCR where obtained with bands in some of the reactions but not in the duplicates. Even the g-Block was not seen though we have easily amplified that before with very bright bands.

208 lab afternoon


Main purposes today


Performing Colony PCR to verify if transformants contain proper construct (signal peptide, GFP, RFP - in plazmid pZA21).

Who was in the lab


Gosia, Ariadni

Procedure


Among colonies which grew after transformation 11 colonies were chosen to be verified by colony PCR. Plates with transformants and colonies checked by colony PCR are signed:

  1. T2 U2 Sec - colonies 01, 02, 03
  2. T2 U2 TAT2 - colonies 01, 02, 03
  3. T2 U3 TAT3 - colonies 01, 02, 03, 1a, 2a

T2 U2 Sec stands for 2nd transformation, 2nd USER reaction, Sec signal peptide TAT2 and TAT3 is TAT signal peptide

All checked colonies were plated on a new plate, overnight incubation at 37°C.

PCR master mix for 12 samples (one additional just in case) was done according to Colony PCR method. Forward primer for colonies with Sec signal (PCR tubes signed: 1, 2, 3) peptide was primer for GFP Sec FW (5a). Forward primer for colonies (PCR tubes signed: 4, 5, 6, 7, 8, 9, 10, 11) with TAT was GFP TAT FW (4a). Reversed primer for all colonies was RFP RW (6b n).

In positive colonies amplified fragment of lenght about 1550 bp is expected.

PCR program (IGEM_CO)

  1. 98°C for 2:00
  2. 98°C for 0:10
  3. 67°C for 0:05
    • ramp 0.1°C/s until 62°C
  4. 72°C for 1:30
  5. Go to number 2 - repeat 50
  6. 72°C for 5:00
  7. 4°C for 10:00:00
