Highly specific and rigorously validated in-house, CD19 (Intracellular Domain) (D4V4B) Rabbit Monoclonal Antibody (SignalFlex\u003csup\u003e™\u003c\/sup\u003e mFluor\u003csup\u003e™\u003c\/sup\u003e Violet 510 Conjugate) (CST #88981) is ready to ship.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nSignalFlex™ conjugates are produced using highly validated Cell Signaling Technology ® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays. Optimal dilutions\/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate.\n\u003cb\u003eStorage\u003c\/b\u003e\nSupplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg\/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.\n\u003cb\u003eSpecificity \/ Sensitivity\u003c\/b\u003e\nCD19 (Intracellular Domain) (D4V4B) XP\nSpecies Reactivity: Human, Mouse, Monkey\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu427 of human CD19 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nCD19 is a 95 kDa coreceptor which amplifies the signaling cascade in B cells (1). On the B cell surface, CD19 associates with CD21, CD81, and Leu-13 to exert its function. The cytoplasmic tail of CD19 has nine conserved tyrosine residues playing critical roles in CD19 mediated function by coupling signaling molecules to the receptor (1). After B cell receptor or CD19 ligation, Tyr531 and Tyr500 of CD19 are progressively phosphorylated. This phosphorylation enables the coupling of PI3 kinase and Src family tyrosine kinase to CD19 and activates the PI3K and Src signaling pathways (2,3). Coligation of B cell receptor and CD19 also promotes Tyr409 phosphorylation in CD19. The phosphorylation at these sites enables its binding to Vav and mediates elevated intracellular calcium response, as well as the JNK pathway (4,5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nB-lymphocyte antigen CD19; B-lymphocyte surface antigen B4; B4; CD19; CD19 antigen; CD19 molecule; CVID3; Differentiation antigen CD19; MGC12802; T-cell surface antigen Leu-12\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M Mk\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800552755369,"sku":"88981W2","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-88981w2","provider":"Iright","version":"1.0","type":"link"}
