Hello Patrick,
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.

Good Luck
