CD19 is a member of the Ig superfamily and is the dominant component for the signaling complex on B cells that includes CD21, CD81, and CD22. Humans with CD19 deficiency have reduced proliferative responses to BCR stimulation in vitro and mount impaired Ab responses to vaccination.\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: human, mouse, rat\nCited Reactivity: human, mouse, rat\nHost \/ Isotype: Rabbit \/ IgG\nClass: Polyclonal\nType: Antibody\nImmunogen: CatNo: Ag27656 Product name: Recombinant human CD19 protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 456-556 aa of BC006338 Sequence: SNAESYENEDEELTQPVARTMDFLSPHGSAWDPSREATSLGSQSYEDMRGILYAAPQLRSIRGQPGPNHEEDADSYENMDNPDGPDPAWGGGGRMGTWSTR Predict reactive species\nFull Name: CD19 molecule\nCalculated Molecular Weight: 556 aa, 61 kDa\nObserved Molecular Weight: 95 kDa\nGenBank Accession Number: BC006338\nGene Symbol: CD19\nGene ID (NCBI): 930\nENSEMBL Gene ID: ENSG00000177455\nRRID: AB_2881019\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Antigen affinity purification\nUNIPROT ID: P15391\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
