Purification of gonadotropin II from a teleost fish, the hybrid striped bass, and development of a specific enzyme-linked immunosorbent assay.

A highly purified gonadotropin II (GtH II), referred to as striped bass GtH II (stbGtH II), and its alpha and beta subunits were prepared from pituitaries of sexually mature hybrid striped bass. Pituitary glycoproteins were extracted with ethanol and intact stbGtH II purified by gel-filtration chromatography on Sephadex G-100, ion-exchange chromatography… CONTINUE READING
