Re: experiences with pET vectors from Novagen

I first cloned my protein - a small DNA binding protein - into a GST
fusion for expression and ended up with lots of degradation or truncated
proteins, even in a protease-deficient bacterial strain.  I have now put
it into a pET vector with a His-tag and express it in BL21(DE3)/pLysS and
get good expression with single step purification on their affinity
matrix with no degradation.  I!m happy.
