Product Description	Recombinant Biotinylated Human SIRP alpha V6 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Glu31-Arg370(S105P).
Product Background	Signal regulatory protein α (SIRPα) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons.SIRPα acts as inhibitory receptor and interacts with a broadly expressed transmembrane protein CD47 also called the "don´t eat me" signal.Cancer cells highly expressed CD47 that activate SIRP α and inhibit macrophage-mediated destruction.
Product Category	Recombinant Protein / Antibody discovery / Immune checkpoint proteins
