MACROPHAGE ACTIVATING FACTOR FROM ANIMAL VITAMIN D-BINDING PROTEIN

摘要

A novel macrophage activating factor is prepared in vitro by treatingglycosylated animal vitamin D-binding protein withglycosidases. Vitamin, D-binding protein; which is isolated from blood orplasma of animals by known procedures, is thus readilyconverted to a highly potent macrophage activating factor.
