Human CD47, Fc fusion protein, also known as leukocyte surface antigen CD47, integrin-associated protein (IAP), OA3, and MER6, GenBank Accession No. NM_001777, a.a. 19-139, with C-terminal Avi-Tag, expressed in a HEK293 cell expression system. The purified protein (40 kDa) was covalently labeled by streptavidin (~13 kDa). Protein runs at a higher MW by SDS-PAGE due to glycosylation and streptavidin labeling.

leukocyte surface antigen CD47, Rh-related antigen, integrin-associated protein, antigenic surface determinant protein OA3, antigen identified by monoclonal antibody 1D8, IAP, MER6.
