Detection of Human CD46 by Western Blot. Western blot shows lysate of human skin tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human CD46 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2005) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CD46 at approximately 50-70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
CD46 in Human Skin. CD46 was detected in immersion fixed paraffin-embedded sections of human skin using 1.7 µg/mL Goat Anti-Human CD46 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2005) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

CD46, also known as MCP (complement membrane cofactor protein), is a type I membrane protein that has cofactor activity for inactivation of complement components C3b and C4b by serum factor I. CD46 is widely distributed in white blood cells, platelets, epithelial cells and fibroblasts. At least fourteen different transcript variants encoding different isoforms have been reported for this gene.
