Product Summary for Mouse Pentraxin 3/TSG-14 Quantikine ELISA Kit
The Quantikine Mouse Pentraxin 3 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse PTX3 in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant mouse PTX3 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse PTX3 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 PTX3.

Recovery for Mouse Pentraxin 3/TSG-14 Quantikine ELISA Kit
The recovery of mouse PTX3 spiked to three levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 107 | 98-119 |
| EDTA Plasma (n=4) | 98 | 90-110 |
| Heparin Plasma (n=4) | 95 | 81-100 |
| Serum (n=4) | 102 | 90-117 |
Linearity
To assess the linearity of the assay, samples containing or spiked with high concentrations of mouse PTX3 in each matrix were diluted with Calibrator Diluent and assayed.
