Western blotting after SDS-PAGE of osteoclast plasma membranes (OC-PM) (30 μg protein) and osteoblast postnuclear membranes (OB-PNM) (50 μg protein) using an antagonist anti-CD38 antibody (Sigma Chemical Co.). We identified 46-kD bands with an additional lower molecular weight band in OC-PMs. The osteoclast preparations were >99% pure as assessed by TRAP staining (see Materials and Methods).
