The effects of synthetic thymopoietin on binding of alpha-bungarotoxin to rat neural membranes

Comp Biochem Physiol C Comp Pharmacol Toxicol. 1993 Mar;104(3):411-3. doi: 10.1016/0742-8413(93)90010-i.

Abstract

Chemically synthesized bovine thymopoietin I (TPO-I) and thymopoietin II (TPO-II) were evaluated as inhibitors of 125I alpha-Bungarotoxin binding to rat brain neural membranes and found to be over 1,000 x less potent (IC50 = 10 microM) than reported for thymopoietin isolated from bovine thymus.
