It recognizes human CD21 (CR2), a 145 kDa type I integral membrane glycoprotein. CD21 is a receptor for the C3d complement fragment and for the Epstein-Barr virus, expressed on mature B cells, follicular dendritic cells, and some epithelial cells. It plays a role in B cell activation and proliferation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormulation:\u003c\/strong\u003e Solution at 1.0 mg\/mL in PBS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReferences:\u003c\/strong\u003e Carroll, M.C.
