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.
