Signal regulatory protein-alpha (SIRP-α), also known as Tyrosine-protein phosphatase non-receptor type substrate 1, CD172a, Bit, and MyD-1, GenBank Accession No. NM_080792, a.a. 27-370, with C-terminal His-tag, MW 38.4 kDa*, expressed in a HEK293 expression system. This protein acts as a receptor for CD47; a.a. 27-370 correspond to the extracellular portion of SIRP-α. *Note: SIRP-α is heavily glycosylated, resulting in apparent higher molecular weight.
