Product Summary for Mouse Pentraxin 2/SAP Quantikine ELISA Kit
The Quantikine Mouse PTX2/SAP Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse PTX2/SAP in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant mouse PTX2/SAP and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant factor accurately. Results obtained using natural mouse PTX2/SAP 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 mouse PTX2/SAP.

|---|---|---|
| Cell Culture Samples (n=6) | 97 | 81-112 |
Linearity
To assess the linearity of the assay, samples containing high concentrations of mouse PTX2/SAP were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
