Detects and quantifies the level of c-Kit protein independent of its phosphorylation state in human cells. c-Kit is a member of the receptor tyrosine kinase subfamily that includes PDGF, CSF-1, and FLT-3/flk-2 receptors. It plays a critical role in controlling a variety of cellular functions in hematopoietic stem cells, mast cells, melanocytes, and germ cells.

| Data | |||
|---|---|---|---|
 The sensitivity of this ELISA was compared to immunoblotting using known quantities of c-Kit. The data show that the sensitivity of the ELISA is approximately 4X greater than that of immunoblotting. The bands shown in the immunoblot data were developed using a rabbit anti-c-Kit antibody and chemiluminescent detection.  Mo7e cells were treated with Stem Cell Factor (SCF) at varying concentrations (1 to 100 ng/ml) for 10 min, lysed, and quantitated in parallel for total c-Kit and c-Kit (pTyr<sup>823</sup>) expression. The amount of total c-Kit remains relatively constant, while the level of phosphorylation at Tyr<sup>823</sup> increases with the dose of SCF. The results correlate very well with immunoblot of the same samples (inset). |
