Who was in the lab


Kristian, Helen, Henrike, Julia

Procedure


PCR to linearize pZA21::RFP::araBAD

  • Template: pZA21::RFP::araBAD
  • Primers: 55a and 55b
  • Program:
temperature time cycles
98C 2:00 -
98C 0:10 36
65C 1:00 36
72C 3:00 36
72C 5:00 -
10C hold -

The table shows the composition of each reaction:

component (per reaction) 1 2 3 4 5 6 Neg
dNTPs 1uL 1uL 1uL 1uL 1uL 1uL -
buffer (GC/HF + volume) HF + 10uL HF + 10uL HF + 10uL GC + 10uL HF + 10uL HF + 10uL HF + 10uL
X7 polymerase 0.5uL 0.5uL 0.5uL 0.5uL 0.5uL 0.5uL 0.5uL
MilliQ water 29uL 21.5uL 31.5uL 29uL 31.5uL 31.5uL 32.5uL
template 1uL 1uL 1uL 1uL 1uL 1uL -
FW primer 55a 3uL 3uL 3uL 3uL 3uL 3uL 3uL
RV primer 55b 3uL 3uL 3uL 3uL 3uL 3uL 3uL
DMSO (100%) 2.5uL (5%) - - 2.5uL (5%) - - -
Betaine (5M) - 10uL (1M) - - - - -


Repeated reaction mix number 1 and ran on same program to get more backbone.

Two samples were lost because the lids opened during the PCR reaction and sample evaporated.

Conclusion


Something is definitely wrong with our gels. It seems the gradient PCR did not give the right product. Amplification of the linearized pZA21::ara worked.
