Highly specific and rigorously validated in-house, Phospho-Zap-70 (Tyr319)\/Syk (Tyr352) (65E4) Rabbit Monoclonal Antibody (SignalFlex\u003csup\u003e™\u003c\/sup\u003e Alexa Fluor\u003csup\u003e®\u003c\/sup\u003e 700 Conjugate) (CST #77762) 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.

Following TCR engagement, Zap-70 is rapidly phosphorylated on several tyrosine residues through autophosphorylation and transphosphorylation by the Src family tyrosine kinase Lck (2-6). Tyrosine phosphorylation correlates with increased Zap-70 kinase activity and downstream signaling events. Expression of Zap-70 is correlated with disease progression and survival in patients with chronic lymphocytic leukemia (7,8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n70 kDa zeta-associated protein; 70 kDa zeta-chain associated protein; ADMIO2; DKFZp313N1010; FLJ17670; FLJ17679; FLJ25043; FLJ37489; IMD48; KSYK; p72-Syk; spleen associated tyrosine kinase; Spleen tyrosine kinase; SRK; STCD; STD; SYK; Syk-related tyrosine kinase; Tyrosine-protein kinase SYK; Tyrosine-protein kinase ZAP-70; TZK; ZAP-70; ZAP70; zeta chain of T cell receptor associated protein kinase 70; zeta chain of T cell receptor associated protein kinase 70kDa; zeta-chain (TCR) associated protein kinase 70kDa; zeta-chain associated protein kinase, 70kD\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800529686697,"sku":"77762W2","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-77762w2","provider":"Iright","version":"1.0","type":"link"}
