Product Summary for Mouse/Rat Leptin Quantikine ELISA Kit
The Quantikine® Mouse/Rat Leptin Immunoassay is a 4.0 hour solid phase ELISA designed to measure mouse or rat Leptin in cell culture supernates, tissue homogenates, serum, and plasma. It contains E.
coli-expressed recombinant mouse Leptin and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse Leptin accurately. Results obtained for naturally occurring mouse or rat Leptin 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 natural mouse or rat Leptin.

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

Recovery for Mouse/Rat Leptin Quantikine ELISA Kit
The recovery of mouse/rat Leptin spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Mouse Cell Culture Media (n=4) | 109 | 98-117 |
| Mouse EDTA Plasma (n=4) | 96 | 89-110 |
| Mouse Heparin Plasma (n=4) | 90 | 80-105 |
| Mouse Serum (n=4) | 95 | 90-102 |
| Rat EDTA Plasma (n=4) | 106 | 99-113 |
| Rat Heparin Plasma (n=4) | 98 | 91-108 |
| Rat Serum (n=4) | 98 | 91-103 |
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 assayed.
