Although not a member of the tetraspanin superfamily of cell surface receptors, it crosses the cell membrane four times. The CD20 antigen is present on human pre B lymphocytes and on B lymphocytes at all stages of maturation, except on plasma cells. Low level expression of the CD20 antigen has been detected on normal T lymphocytes. The CD20 molecule is involved in regulation of B cell differentiation, presumably via its reported function as a Ca++ channel subunit.\u003c\/p\u003e\n\n\u003cp\u003ePurification and Purity: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
