Effects of 3-aminobenzamide on the induction of gamma-glutamyl-transpeptidase-positive foci by various chemicals in rat liver.

abstract：:To be capable of selective killing of tumor cells, the non-selective Pseudomonas aeruginosa exotoxin A must have its cell-binding domain inactivated or removed and then be chemically linked to, or genetically fused with, a specific targeting agent. In the present study, epsilon-NH2 groups of lysine residues of the cel...
