Assemble pdCas9-w:
Open pdCas9 by PCR

We received plasmid pdCas9 in bacteria. We did a Miniprep (cf. Protocols) on overnight cultures to isolate it.

Materials and method

  • 20 µl Phusion PCR (cf. Protocols) with 1 ng pdCas9 testing parameters such as HF vs. GC buffer, annealing temperatures and extension times
  • PCR product purification (cf. Protocols)
  • Agarose gel electrophoresis of purified PCR products

Results

After testing many parameters, we were able to amplify the plasmid succesfully, as seen on gel above.
For further steps sample from lane 1 was used. Its parameters were: HF buffer, annealing temperature 59°C, extension time 2 minutes 30 seconds.
