The expression of CD22 is developmentally regulated. It is expressed at low levels in the cytoplasm of pro-B and pre-B cells and present on the cell surface only at mature stages of B-cell differentiation. Cell surface expression is lost during terminal differentiation into plasma cell and after B-cell activation. CD22 is an inhibitory receptor for B-cell receptor (BCR) signalling, preferentially binds to alpha-2,6-linked sialic acid and mediates B-cell B-cell interactions. It plays a crucial role in activation and differentiation of the B-cell.\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: human\nCited Reactivity: human\nHost \/ Isotype: Rabbit \/ IgG\nClass: Polyclonal\nType: Antibody\nImmunogen: CatNo: Ag16607 Product name: Recombinant human CD22 protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 166-515 aa of BC109306 Sequence: ILHSPAVEGSQVEFLCMSLANPLPTNYTWYHNGKEMQGRTEEKVHIPKILPWHAGTYSCVAENILGTGQRGPGAELDVQYPPKKVTTVIQNPMPIREGDTVTLSCNYNSSNPSVTRYEWKPHGAWEEPSLGVLKIQNVGWDNTTIACAACNSWCSWASPVALNVQYAPRDVRVRKIKPLSEIHSGNSVSLQCDFSSSHPKEVQFFWEKNGRLLGKESQLNFDSISPEDAGSYSCWVNNSIGQTASKAWTLEVLYAPRRLRVSMSPGDQVMEGKSATLTCESDANPPVSHYTWFDWNNQSLPYHSQKLRLEPVKVQHSGAYWCQGTNSVGKGRSPLSTLTVYYSPETIGRR Predict reactive species\nFull Name: CD22 molecule\nCalculated Molecular Weight: 847 aa, 95 kDa\nObserved Molecular Weight: 120-140 kDa\nGenBank Accession Number: BC109306\nGene Symbol: CD22\nGene ID (NCBI): 933\nRRID: AB_2878937\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Antigen affinity purification\nUNIPROT ID: P20273\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
