Purity：Purified by Protein A affinity chromatography.
Form：Supplied as a lyophilized powder from PBS, pH 7.2, 0.09% sodium azide, 1% BSA. Labeled with R. Phycoerythrin (RPE). Reconstitute with 1ml sterile 40-50% glycerol, ddH2O.
Specificity：Recognizes the human CD46 cell surface antigen, a broadly expresed glycoprotein also known as membrane co-factor protein (MCP).CD46 functions as an inhibitor of complement activation limiting the formation and activity of C3 convertases. CD46 is expressed by all nucleated cells, often as multiple isoforms on the same cells. The molecule is also expressed by sperm and may be important in the process of fertilization.
