E.coli recombinant protein proteolysis troubleshooting
We've been trying to express a pro-hormone as a GST fusion in E. coli (DH5-alpha) but seem to be having problems with proteolysis - we think this may be occuring at double basic sites but are not completely sure. ... ... Click following links ...

need help for the transformation troubleshooting
I want to construct a DNA library with different sequence. First step, PCR, the template contained random 40mers in the middle and normal sequence on each end. After the PCR, I could obtain the PCR product library and I ligated them into the plasmid v ...
