I recently came across a paper (Chen et al, JBC, vol 277, pp4747-4254, 2000) that describes a myrisytolated PKCa/b peptide (MPKCP) inhibitor of PKC a/b activation following Clostridium Difficile Toxin A treatment in T84 cells. There is no mention of the source of this peptide. I wondered if you could buy it commercially. Thanks, Tuc Ahmad ---
