Product Summary for Mouse Neutrophil Elastase/ELA2 Quantikine ELISA Kit
The Quantikine® Mouse Neutrophil Elastase/ELA2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure ELA2 in cell culture supernates, tissue lysates, serum, and plasma. It contains NS0-expressed recombinant mouse ELA2 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant mouse ELA2. Results obtained using natural mouse ELA2 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 ELA2.

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.

Recovery for Mouse Neutrophil Elastase/ELA2 Quantikine ELISA Kit
The recovery of mouse ELA2 spiked to three levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 96 | 90-102 |
| Cell Lysis Buffer (n=3) | 96 | 91-97 |
| EDTA Plasma (n=4) | 108 | 95-125 |
| Heparin Plasma (n=4) | 108 | 101-118 |
| Serum (n=4) | 112 | 104-122 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of mouse ELA2 were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.
