Product Summary for Human C-Reactive Protein/CRP Quantikine ELISA Kit
The Quantikine Human C-Reactive Protein/CRP Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human CRP in cell culture supernates, serum, and plasma. It contains recombinant human CRP and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CRP 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 natural human CRP.

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.

Recovery for Human C-Reactive Protein/CRP Quantikine ELISA Kit
The recovery of human CRP spiked to levels throughout the range of the assay in cell culture media was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 93 | 88-100 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human CRP were serially diluted with the calibrator diluent to produce samples with values within the dynamic range of the assay.
