Abstract
An assay is proposed, based on the increase in the tibial cartilage of the immature hypophysectomized rat. Values for normal individuals in terms of the Armour Standard 22 KR2 varied from 0 to 40 [mu]g/ml No such material was found in panhypopituitarism whereas excessive amounts were found in active acromegaly.
