Our lab uses the GST system from Pharmacia. You get a fusion protein with
Glutathione-S-Transferase and can cleave with your choice of proteases. I
have used pGEX-2T with success, although I have had problems getting my
protein cleaved away from the GST. I didn't need my protein absolutely
pure, so it wasn't important. Another person in the lab has used pGEX-2T &
pGEX-2TK with good success. The latter vector is usefull in that it has a
protein kinase site after the protease site, but in front of your protein
that you can lable stinking hot with gamma 32 ATP.
