It is expressed by B cells and follicular dendritic cells. CD19 is up-regulated at the step of B-lineage commitment during the differentiation of the hematopoietic stem cell, it remains on during subsequent stages of differentiation until finally down-regulated during terminal differentiation into plasma cells (PMID: 8528044). CD19 is involved in B cell development, activation and differentiation. It is the dominant component for the signaling complex on B cells that includes CD21 (CR2), CD81 (TAPA-1) and CD225 and acts as a critical co-receptor for BCR signal transduction (PMID: 23210908).\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: mouse, rat\nHost \/ Isotype: Rabbit \/ IgG\nClass: Polyclonal\nType: Antibody\nImmunogen: CatNo: Eg0907 Product name: Recombinant Mouse CD19 protein (His Tag) Source: mammalian cells -derived, pCMV (S18) Tag: C-6*HIS Domain: 19-287 aa of NM_009844.2 Sequence: RPQKSLLVEVEEGGNVVLPCLPDSSPVSSEKLAWYRGNQSTPFLELSPGSPGLGLHVGSLGILLVIVNVSDHMGGFYLCQKRPPFKDIWQPAWTVNVEDSGEMFRWNASDVRDLDCDLRNRSSGSHRSTSGSQLYVWAKDHPKVWGTKPVCAPRGSSLNQSLINQDLTVAPGSTLWLSCGVPPVPVAKGSISWTHVHPRRPNVSLLSLSLGGEHPVREMWVWGSLLLLPQATALDEGTYYCLRGNLTIERHVKVIARSAVWLWLLRTGG Predict reactive species\nFull Name: CD19 antigen\nCalculated Molecular Weight: 60 kDa\nGenBank Accession Number: NM_009844.2\nGene Symbol: Cd19\nGene ID (NCBI): 12478\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Antigen affinity Purification\nUNIPROT ID: P25918\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
