Product Summary for Mouse/Rat Angiopoietin-2 Quantikine ELISA Kit
The Quantikine Mouse/Rat Angiopoietin-2 Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse and rat Angiopoietin-2 in cell culture supernates, tissue lysates, serum, and plasma. It contains CHO cell-expressed recombinant mouse Angiopoietin-2 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant factor accurately. Results obtained using natural Angiopoietin-2 showed dose-response curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural Angiopoietin-2.

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 kit components.

Recovery for Mouse/Rat Angiopoietin-2 Quantikine ELISA Kit
The recovery of Angiopoietin-2 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Samples (n=4) | 114 | 108-120 |
| EDTA Plasma (n=2) | 105 | 101-110 |
| Heparin Plasma (n=2) | 107 | 103-111 |
| Serum (n=2) | 113 | 109-117 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Angiopoietin-2 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
