The PathScan® Phospho-Syk (Tyr525/526) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of Syk when phosphorylated at tyrosine 525/526. A phospho-Syk (Tyr525/526) Rabbit mAb has been coated onto the microwells. After incubation with cell lysates, Syk phosphorylated at Tyrosine525/526 is captured by the coated antibody. Following extensive washing, a Syk mouse monoclonal detection antibody is added to detect the captured Syk protein. HRP-linked, Anti-mouse Ab is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of Syk phosphorylated on Tyr525/526.Antibodies in kit are custom formulations specific to kit.

Background: Syk is a protein tyrosine kinase that plays an important role in intracellular signal transduction in hematopoietic cells (1-3). Syk interacts with immunoreceptor tyrosine-based activation motifs (ITAMs) located in the cytoplasmic domains of immune receptors (4). It couples the activated immunoreceptors to downstream signaling events that mediate diverse cellular responses, including proliferation, differentiation, and phagocytosis (4). There is also evidence of a role for Syk in nonimmune cells and investigators have indicated that Syk is a potential tumor suppressor in human breast carcinomas (5). Tyr323 is a negative regulatory phosphorylation site within the SH2-kinase linker region in Syk. Phosphorylation at Tyr323 provides a direct binding site for the TKB domain of Cbl (6,7). Tyr352 of Syk is involved in the association of PLCγ1 (8). Tyr525 and Tyr526 are located in the activation loop of the Syk kinase domain; phosphorylation at Tyr525/526 of human Syk (equivalent to Tyr519/520 of mouse Syk) is essential for Syk function (9).

The PathScan® Phospho-Src (Tyr416) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-Src (Tyr416). A phospho-Src rabbit antibody has been coated onto the microwells. After incubation with cell lysates, phospho-Src (Tyr416) is captured by the coated antibody. Following extensive washing, a Src mouse detection antibody is added to detect the captured phospho-Src (Tyr416). Anti-mouse, HRP-linked antibody is then used to recognize the bound detection antibody. The HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of phospho-Src (Tyr416).Antibodies in kit are custom formulations specific to kit.

Background: The Src family of protein tyrosine kinases, which includes Src, Lyn, Fyn, Yes, Lck, Blk, and Hck, are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. While phosphorylation at Tyr416 in the activation loop of the kinase domain upregulates enzyme activity, phosphorylation at Tyr527 in the carboxy-terminal tail by Csk renders the enzyme less active (2).

CST's PathScan® Total VEGFR-2 Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of total VEGFR-2 protein. A VEGFR-2 Mouse mAb (7335-1D6*) has been coated onto the microwells. After incubation with cell lysates, Both nonphospho- and phospho-VEGFR-2 proteins are captured by the coated antibody. Following extensive washing, a VEGFR-2 Rabbit mAb (7340-55B11*) is added to detect the captured VEGFR-2 protein. HRP-linked anti-rabbit antibody (#7074*) is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of optical density for this developed color is proportional to the quantity of total VEGFR-2 protein.* Antibodies in this kit are custom formulations specific to the kit.

Background: Vascular endothelial growth factor receptor 2 (VEGFR2, KDR, Flk-1) is a major receptor for VEGF-induced signaling in endothelial cells. Upon ligand binding, VEGFR2 undergoes autophosphorylation and becomes activated (1). Major autophosphorylation sites of VEGFR2 are located in the kinase insert domain (Tyr951/996) and in the tyrosine kinase catalytic domain (Tyr1054/1059) (2). Activation of the receptor leads to rapid recruitment of adaptor proteins, including Shc, GRB2, PI3 kinase, NCK, and the protein tyrosine phosphatases SHP-1 and SHP-2 (3). Phosphorylation at Tyr1212 provides a docking site for GRB2 binding and phospho-Tyr1175 binds the p85 subunit of PI3 kinase and PLCγ, as well as Shb (1,4,5). Signaling from VEGFR2 is necessary for the execution of VEGF-stimulated proliferation, chemotaxis and sprouting, as well as survival of cultured endothelial cells in vitro and angiogenesis in vivo (6-8).
