Product Summary for Human Serpin C1/Antithrombin-III Quantikine ELISA Kit
The Quantikine Human Serpin C1/Antithrombin-III Immunoassay is a 3.5 hour solid-phase ELISA designed to measure human Serpin C1 in cell culture supernates, serum, plasma, urine, and human milk. It contains NS0-expressed recombinant human Serpin C1 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Serpin C1 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 human Serpin C1.

Specificity
Natural and recombinant free and complexed human Serpin C1. This assay cross-reacts 1.4% with recombinant mouse Serpin C1.
Cross-reactivity
< 0.5% cross-reactivity observed with available related molecules. Cross-species reactivity observed with 1 or more species tested.
Interference
No significant interference observed with available related molecules.
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 using two lots of components.

Recovery for Human Serpin C1/Antithrombin-III Quantikine ELISA Kit
The recovery of human Serpin C1 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 93 | 83-108 |
| Urine (n=4) | 99 | 92-109 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human Serpin C1 were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
