Study on the purification of growth hormone-like substance from pituitaries of the snake Ptyas mucosa.
Extract from the snake (Ptyas mucosa) pituitaries was capable of inhibiting the binding of 125I-labelled bovine growth hormone to female rat liver membranes. The growth hormone-like substance was not adsorbed on Concanavalin A-Sepharose nor DEAE-cellulose, but could be purified by gel filtration on Sephadex G-50. It possessed a molecular weight of about 19,000 as judged by SDS-polyacrylamide gel electrophoresis. The iodinated snake growth hormone-like substance bound to membranes prepared from female rat and pregnant rabbit livers. The binding could be inhibited by unlabelled snake growth hormone-like substance as well as by bovine growth hormone.
