Product Summary for Human CD117/c-kit Quantikine ELISA Kit

The Quantikine Human SCF sR Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human SCF sR in cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant human SCF sR and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human SCF sR showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human SCF sR.

Recovery for Human CD117/c-kit Quantikine ELISA Kit

The recovery of SCF sR spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 103 97-110
EDTA Plasma (n=4) 91 84-106
Heparin Plasma (n=4) 92 87-102
Serum (n=4) 93 86-115

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of SCF sR were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: CD117/c-kit

CD117, also known as c-kit and SCF R, is the cellular receptor for Stem Cell Factor (SCF), also named c-kit ligand, mast cell growth factor, and steel factor. This receptor-ligand system plays essential roles in germ cell development, melanogenesis, hematopoiesis, and oncogenesis. CD117 is expressed on lymphoid, myeloid, erythroid, and megakaryocyte progenitors, NK cells, germ cells, melanocytes, glial cells, vascular smooth muscle cells, placenta, and epithelial cells. Altered levels and mutations in CD117 are associated with several types of cancer including lung, breast, gastrointestinal stromal, and germ cell tumors.
