Abstract
Complementation of the plasmin fragments of reduced-carbamoylmethylated (Cam) human somatotropin (hGH) with those of reduced-carbamoylmethylated human chorionic somatomammotropin (hCS) have been investigated. It was found that the recombinant obtained by noncovalent interaction of [Cys(Cam)53]hGH-(1-134) with [Cys(Cam)-165,182,189]hCS-(141-191) exhibits 50% growth-promoting activity and nearly full immunoreactivity. Complementation of [Cys(Cam)53]hCS-(1-133) with the COOH-terminal fragment of hGH generated lower growth-promoting and immunological activities.
