Product Summary for Mouse IL-7 Quantikine ELISA Kit
The Quantikine Mouse IL-7 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse IL-7 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mouse IL-7 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse IL-7 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 mouse IL-7.

Recovery for Mouse IL-7 Quantikine ELISA Kit
The recovery of mouse IL-7 spiked to three levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (n=6) | 110 | 107-113 |
| EDTA Plasma (n=4) | 109 | 100-118 |
| Serum (n=4) | 108 | 96-120 |
Linearity
To assess the linearity of the assay, samples spiked with high concentrations of mouse IL-7 in each matrix were diluted with Calibrator Diluent and then assayed.

Background: IL-7
IL-7 (Interleukin-7) is a cytokine that plays important roles in lymphocyte differentiation, proliferation, and survival. IL-7 is produced by stromal epithelial cells of the thymus, bone marrow, and intestines. It signals through a receptor complex composed of IL-7 R alpha/CD127 and the Common gamma Chain. gamma c is also a subunit of the receptors for IL-2, -4, -9, -15, and -21. IL-7 contributes to the maintenance of all naïve and memory T cells. It is required for optimal T cell-dendritic cell interaction. In mouse, IL-7 activation of IL-7 R alpha is critical for both T cell and B cell lineage development, while in humans, it is required for T cell but not for B cell development.
