It is mapped to 11q12.2. This gene encodes a member of the membrane-spanning 4A gene family. The function of CD20 is to enable optimal B-cell immune response, specifically against T-independent antigens. It is suspected that CD20 acts as a calcium channel in the cell membrane. What’s more, this protein may be involved in the regulation of B-cell activation and proliferation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e: E.coli-derived human CD20\/MS4A1 recombinant protein (Position: M1-P297).\u003c\/p\u003e\u003cp\u003e\u003cb\u003eClonality\u003c\/b\u003e: Monoclonal\u003c\/p\u003e\u003cp\u003e\u003cb\u003eContents\u003c\/b\u003e: Each vial contains 4 mg Trehalose, 0.9 mg NaCl and 0.2 mg Na2HPO4.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification\u003c\/b\u003e: Immunogen affinity purified.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Adding 0.2 ml of distilled water will yield a concentration of 500 μg\/ml.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: 1.
