Product Summary for Human IL-28B/IFN-lambda 3 Quantikine ELISA Kit
The Quantikine Human IL-28B/IFN-lambda 3 Immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-28B levels in cell culture supernates, cell lysates, serum, EDTA plasma, and urine. It contains CHO cell-expressed recombinant human IL-28B and antibodies raised against the recombinant protein. Results obtained for naturally occurring human IL-28B showed linear curves that were parallel to the standard curves obtained using the Quantikine Human IL-28B Immunoassay standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-28B.

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 IL-28B/IFN-lambda 3 Quantikine ELISA Kit
The recovery of human IL-28B spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 113 | 83-122 |
| Cell Lysis Buffer (n=4) | 96 | 87-103 |
| EDTA Plasma (n=4) | 111 | 93-124 |
| Serum (n=4) | 111 | 96-124 |
| Urine (n=4) | 84 | 75-96 |
Linearity
To assess the linearity of the assay, samples spiked with high concentrations of human IL-28B were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
