I recently posted to this news group concerning the use of a Clontech
two-hybrid library with thier vector (pGBT9). Firstly I had poor
expression from thier vector. Secondly, I had about 6 replies to my
posting, and apart from the one from Clontech....nobody had anything good
to say about thier system.
I switched to pAS-1 and have had great expression from that. I have at
last had some success (even using the Clontech library) in a screen using
pAS-1 and am working through the 50 positives (although that number could
easily just be artifacts!!).
