Product Summary for Human COMP Quantikine ELISA Kit
The Quantikine Human COMP immunoassay is a 4.5 hour solid phase ELISA designed to measure human COMP in cell culture supernates, cell lysates, serum, and plasma. It contains NS0-expressed recombinant human COMP and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human COMP 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 COMP.

Recovery for Human COMP Quantikine ELISA Kit
The recovery of COMP spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=5) | 103 | 95-111 |
| Cell Lysates (n=1) | 102 | 98-108 |
| EDTA Plasma (n=4) | 103 | 86-114 |
| Heparin Plasma (n=4) | 99 | 88-112 |
| Serum (n=4) | 102 | 86-114 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human COMP were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
