CD21 is expressed on B cells, follicular dendritic cells, subsets of normal thymocytes and T cells, and some epithelial cells. CD21 is the receptor used by Epstein-Barr virus to infect B cells and is also the complement receptor for C3d. CD21 has also been shown to interact with a number of proteins, including CD23, CD19, annexin VI, CD81, iC3b, complement receptor 1 (CR1, CD35), and interferon-alpha 1 (IFN-α1).\u003c\/p\u003e\n\n\u003ch2\u003eValidated Applications \u0026amp; Recommended Dilutions\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003cth\u003eRecommended Dilution\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow Cytometry\u003c\/td\u003e\n\u003ctd\u003eSee product datasheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eAntibody Specifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget\u003c\/th\u003e\n\u003ctd\u003eCD21\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost Species\u003c\/th\u003e\n\u003ctd\u003eMouse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClonality\u003c\/th\u003e\n\u003ctd\u003eMonoclonal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIsotype\u003c\/th\u003e\n\u003ctd\u003eMouse IgG1, κ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConjugate\u003c\/th\u003e\n\u003ctd\u003eUnconjugated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClone Number\u003c\/th\u003e\n\u003ctd\u003eBU32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurification\u003c\/th\u003e\n\u003ctd\u003eSee datasheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConcentration\u003c\/th\u003e\n\u003ctd\u003e≥ 1 mg\/mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eImmunogen\u003c\/h2\u003e\n\u003cp\u003eRecombinant protein fragment; see full datasheet.
