Product Summary for Human PLA2G7/PAF-AH/Lp-PLA2 Quantikine ELISA Kit
The Quantikine Human PLA2G7 Immunoassay is a 4.5 hour solid phase ELISA designed to measure PLA2G7 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human PLA2G7 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human PLA2G7 showed linear curves that were parallel to the curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human PLA2G7.

Recovery for Human PLA2G7/PAF-AH/Lp-PLA2 Quantikine ELISA Kit
The recovery of PLA2G7 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 92 | 85-105 |
| EDTA Plasma (n=4) | 101 | 91-112 |
| Heparin Plasma (n=4) | 102 | 92-106 |
| Serum (n=4) | 106 | 91-115 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of PLA2G7 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
