CST's PathScan® Phospho-c-Kit (panTyr) Sandwich ELISA Antibody Pair is offered as an economical alternative to our PathScan® Phospho-c-Kit (panTyr) Sandwich ELISA Kit #7231. Capture and Detection Antibodies (100X stocks) and HRP-Conjugated Streptavidin (1000X stock) are supplied. Sufficient reagents are supplied for 4 x 96 well ELISAs. The c-Kit Mouse Capture Antibody is coated in PBS overnight in a 96 well microplate. After blocking, cell lysates are added followed by Biotinylated Phospho-Tyrosine Mouse Detection Antibody and HRP-conjugated streptavidin. HRP substrate, TMB, is added for color development. The magnitude of the absorbance for this developed color is proportional to the quantity of phospho-c-Kit (panTyr) protein.
Antibodies in kit are custom formulations specific to kit.
Specificity / Sensitivity
For Antibody Pair specificity and sensitivity, please refer to the corresponding PathScan® Sandwich ELISA Kit. Note: This antibody pair detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
The relationship between protein concentration of lysates from untreated and SCF-treated H526 lysates and the absorbance at 450 nm is shown. Cells (0.5x106 cells/ml) were serum starved overnight and then treated with Human Stem Cell Factor (hSCF) #8925 (100 ng/ml) for 5 min at 37°C, and then lysed.
c-Kit is a member of the subfamily of receptor tyrosine kinases that includes PDGF, CSF-1, and FLT3/flk-2 receptors (1,2). It plays a critical role in activation and growth in a number of cell types including hematopoietic stem cells, mast cells, melanocytes, and germ cells (3). Upon binding with its stem cell factor (SCF) ligand, c-Kit undergoes dimerization/oligomerization and autophosphorylation. Activation of c-Kit results in the recruitment and tyrosine phosphorylation of downstream SH2-containing signaling components including PLCγ, the p85 subunit of PI3 kinase, SHP2, and CrkL (4). Molecular lesions that impair the kinase activity of c-Kit are associated with a variety of developmental disorders (5), and mutations that constitutively activate c-Kit can lead to pathogenesis of mastocytosis and gastrointestinal stromal tumors (6). Tyr719 is located in the kinase insert region of the catalytic domain. c-Kit phosphorylated at Tyr719 binds to the p85 subunit of PI3 kinase in vitro and in vivo (7).
