Main purpose


  • plasmid isolation
  • colony PCR to verify transformants from 18-07-2013.
  • gel electrophoresis to verify insert after colony PCR (AMO, HAO), plasmid isolation
  • gel electrophoresis to verify plasmid isolation
  • restriction analysis of isolated plasmids
  • gel electrophoresis to verify restriction analysis

Who was in the lab


Gosia, Henrike

Procedure


Plasmid isolation

According to protocol in QIAprep Spin Miniprep Kit

Colony PCR

Master mix was prepared based on standard colony PCR procedure.

For AMO primers 29a, 29b were used (no USER primers this time) and for HAO primers 28a, 28b were used. We used Phusion polymerase. We obtained 7 transformants after yesterday transformation with AMO in pZA21 and 3 transformants which may contain HAO in pZA21. On negative control plate 3 colonies grew.

PCR parameters according to standard reaction with differences in annealing temperatures (for AMO -> 54°C, for HAO -> 56°C) and with 3 min of extension time. Expected fragments lengths are AMO - 3074 bp, HAO - 2816 bp.

Restriction analysis

Restriction analysis was performed with EcoRI enzyme.

Compound Volume uL
DNA (miniprep) 10
Buffer for EcoRI 10x 2
water 7,5
EcoRI enzyme 0,5

Incubation for 1-2 hours at 37°C.
