  • In vitro enzymatic conversion of glycosylated human vitamin D binding protein to a potent macrophage activating factor
    Patent number: 5177002
    Abstract: A novel, potent macrophage activating factor is prepared in vitro by treating glycosylated human group-specific component, also known as human vitamin D-binding protein, with glycosidases. Group-specific component, which is isolated from retired blood by known procedures, is thus readily converted to a highly potent macrophage activating factor.

  • In vitro enzymatic conversion of glycosylated mammalian vitamin D-binding protein to a potent macrophage activating factor
    Patent number: 5177001
    Abstract: A novel macrophage activating factor is prepared in vitro by treating glycosylated mammalian vitamin D-binding protein with glycosidases. Vitamin D-binding protein, which is isolated from blood or plasma of animals by known procedures, is thus readily converted to a highly potent macrophage activating factor.
