Product Summary for Mouse/Rat Leptin Quantikine ELISA Kit
The Quantikine Mouse Leptin Immunoassay is a 4.5 hour solid phase ELISA designed to measure soluble mouse leptin in cell culture supernates, serum*, and plasma. It contains recombinant mouse leptin expressed in E. coli and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse leptin accurately. Results obtained measuring natural mouse leptin showed dose-response 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 natural mouse leptin.
*Pregnant mouse serum from the second trimester of pregnancy through post-partum day 1 require acid/urea activation of mouse leptin.

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Recovery for Mouse/Rat Leptin Quantikine ELISA Kit
The recovery of mouse/rat Leptin spiked to three levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Mouse Cell Culture Supernates (n=5) | 101 | 85-120 |
| Mouse EDTA Plasma (n=4) | 92 | 78-105 |
| Mouse Heparin Plasma (n=4) | 95 | 81-105 |
| Mouse Serum (n=18) | 108 | 81-122 |
| Rat Cell Culture Supernates (n=4) | 114 | 103-125 |
| Rat EDTA Plasma (n=7) | 96 | 83-114 |
| Rat Serum (n=10) | 92 | 81-115 |
Linearity
To assess the linearity of the assay, four or more samples containing and/or spiked with high concentrations of mouse/rat Leptin in each matrix were diluted with Calibrator Diluent and then assayed.
