Description_x000D_ General description_x000D_ Signal regulatory proteinalpha (SIRP-α), also known as Tyrosineprotein phosphatase non-receptor type substrate 1, CD172a, Bit, and MyD-1, GenBank Accession No. NP_542970, a.a. 27-370, with C-terminal Avi and His tags, MW 40.3 kDa*, expressed in a HEK293 expression system and enzymatically biotinylated using Avitag™ technology. 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 higher molecular weight._x000D_ Physical form_x000D_ Aqueous solution_x000D_ Legal Information_x000D_ AviTag is a trademark of Avidity, LLC
