It is expressed on B cells, follicular dendritic cells, thymocytes and a subset of peripheral T cells (PMID: 26119182). CD21 binds complement fragments C3d, C3dg and iC3b and acts as a receptor for the Epstein-Barr virus (PMID: 7753047). On B cells, together with CD19 and CD81, CD21 forms a complex that functions as a co-receptor to the BCR (PMID: 7542009). It is involved in B cells activation and functions.\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: Human\nHost \/ Isotype: Mouse \/ IgG2a\nClass: Monoclonal\nType: Antibody\nImmunogen: CatNo: Ag18058 Product name: Recombinant human CR2 protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 581-930 aa of BC136394 Sequence: QERGTWSGPAPLCKLSLLAVQCSHVHIANGYKISGKEAPYFYNDTVTFKCYSGFTLKGSSQIRCKADNTWDPEIPVCEKGCQSPPGLHHGRHTGGNTVFFVSGMTVDYTCDPGYLLVGNKSIHCMPSGNWSPSAPRCEETCQHVRQSLQELPAGSRVELVNTSCQDGYQLTGHAYQMCQDAENGIWFKKIPLCKVIHCHPPPVIVNGKHTGMMAENFLYGNEVSYECDQGFYLLGEKKLQCRSDSKGHGSWSGPSPQCLRSPPVTRCPNPEVKHGYKLNKTHSAYSHNDIVYVDCNPGFIMNGSRVIRCHTDNTWVPGVPTCIKKAFIGCPPPPKTPNGNHTGGNIARFS Predict reactive species\nFull Name: complement component (3d\/Epstein Barr virus) receptor 2\nCalculated Molecular Weight: 1092 aa, 119 kDa\nObserved Molecular Weight: 150 kDa\nGenBank Accession Number: BC136394\nGene Symbol: CD21\nGene ID (NCBI): 1380\nENSEMBL Gene ID: ENSG00000117322\nRRID: AB_2882054\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Protein A purification\nUNIPROT ID: P20023\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
