title: Endorphin activity in anterior, intermediate, and posterior pituitary.
abstract: The content of endogenous morphine-like substance in bovine pituitary and brain was determined by an opiate radioreceptor assay. The intermediate lobe was most concentrated in activity and the brain least concentrated. Most of the endorphin is obtained in a 120 000 g-min fraction from pituitary or brain homogenates.
