CD63 Antibody, anti-rat, PE, REAfinity™

01MT03434

Clone REA444 recognizes the rat CD63 antigen, a multi-pass membrane protein which is also known as mast cell antigen AD1 or melanoma antigen ME491. CD63 is located on the basophilic granule membranes in resting basophils, mast cells, and platelets, and is also located on the plasma membranes of these cells. It is also found on rat embryonic fibroblasts and hepatic cell. CD63 belongs to the tetraspanin transmembrane 4 superfamily (TM4SF) of proteins, which are characterized by four membrane spanning domains. Tetraspanins, via various homotypic and heterotypic interactions, regulate the spatial
