An Immunological Investigation of Human Pituitary Growth Hormone

Tetsuo Hayashida; Choh Hao Li

Growth hormone isolated from human pituitaries has been demonstrated to be a good antigen in the rabbit. With the rabbit antiserum to human somatotropin, it is possible to detect as little as 0.1 �g of the hormone by precipitin test. The antiserum was also capable of neutralizing the growth-promoting activity of human somatotropin.

Preparation and properties of beef α-core from chymotryptic digestion of bovine growth hormone

Choh Hao Li; Harold Papkoff; Tetsuo Hayashida

Abstract A procedure for the preparation of a biologically active fraction (designated beef α-core) from chymotryptic digests of bovine somatotropin has been described. Certain biological, physicochemical, and immunological aspects of the product have been investigated.
