Recombinant Human CD20/MS4A1 Protein, His -Avi Tag

Description :
FAQ COA 已发表文献 B-lymphocyte antigen CD20 or CD20 is an activated-glycosylated phosphoprotein expressed on the surface of all B-cells beginning at the pro-B phase (CD45R , CD117) and progressively increasing in concentration until maturity.The protein has no known natural ligand and its function is to enable optimal B-cell immune response, specifically against T-independent antigens. 产品性质 Synonyms MS4A1; CD20; MS4A-1; B1; Bp35; CD20 receptor; CD20S7; CVID5; LEU-16; Ly-44; MS4A2; S7 Uniprot No. P11836-1 Source Recombinant Human CD20/MS4A1 Protein is expressed from E.coli with His tag and Avi tag at the C-terminal.
