Product Summary for Human CCL26/Eotaxin-3 Quantikine ELISA Kit
The Quantikine® Human CCL26/Eotaxin-3 Immunoassay is a 4.5 hour solid phase ELISA designed to measure human Eotaxin-3 levels in cell culture supernates, cell lysates, serum, and plasma. It contains E.
coli-expressed, recombinant human Eotaxin-3 and antibodies raised against the recombinant factor. Results obtained for naturally occurring human Eotaxin-3 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 Eotaxin-3.

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 CCL26/Eotaxin-3 Quantikine ELISA Kit
The recovery of human Eotaxin-3 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=5) | 102 | 92-119 |
| Cell Lysis Buffer (n=1) | 97 | 94-99 |
| EDTA Plasma (n=5) | 94 | 84-105 |
| Heparin Plasma (n=5) | 95 | 86-109 |
| Serum (n=5) | 93 | 81-106 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human Eotaxin-3 were diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.
