Recombinant FITC-Labeled Human Siglec-2/CD22 Protein, hFc Tag

Description :
FAQ COA 已发表文献 Human Siglec-2, also known as B-cell antigen CD22 or B-lymphocyte cell adhesion molecule (BL-CAM), is a B-cell restricted glycoprotein that is expressed in the cytoplasm of progenitor B and pre-B cells and on the surface of mature B cells. 产品性质 Synonyms CD22 molecule; CD22; Siglec-2; B-cell receptor CD22; BL-CAM; SIGLEC2; Uniprot No. P20273-1 Source Recombinant FITC-Labeled Human Siglec-2/CD22 Protein is expressed from Expi293 with hFc tag at the C-terminal. It contains Asp20-Arg687. Molecular Weight The protein has a predicted MW of 101.9 kDa. Due to glycosylation, the protein migrates to 130-140 kDa based on Tris-Bis PAGE result. Purity > 95% as determined by SDS-PAGE. Endotoxin 1.0EU per 1g of the protein by the LAL method. Formulation Supplied as 0.22m filtered solution in PBS (pH 7.4).
