It is a member of the protein tyrosine phosphatase (PTP) family with a molecular weight of approximately 180-240 kD. CD45R is expressed on B cells (at all developmental stages from pro-B cells through mature B cells), activated B cells, and subsets of T and NK cells. CD45R (B220) is also expressed on a subset of abnormal T cells involved in the pathogenesis of systemic autoimmunity in MRL-Fas\u003csup\u003elpr\u003c\/sup\u003e and MRL-Fas\u003csup\u003egld\u003c\/sup\u003e mice. It plays a critical role in TCR and BCR signaling. The primary ligands for CD45 are galectin-1, CD2, CD3, and CD4. CD45R is commonly used as a pan-B cell marker; however, CD19 may be more appropriate for B cell specificity.\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\u003eCD45R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost Species\u003c\/th\u003e\n\u003ctd\u003eRat\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\u003eRat IgM, κ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConjugate\u003c\/th\u003e\n\u003ctd\u003eElab Fluor®Violet 450\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClone Number\u003c\/th\u003e\n\u003ctd\u003eRA3.3A 1\/6.1\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\u003e0.5 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.\u003c\/p\u003e\n\n\u003ch2\u003eSpecies Reactivity \u0026amp; Cross-Reactivity\u003c\/h2\u003e\n\u003cp\u003eValidated for: Mouse.
