Product Summary for Human CXCL11/I-TAC Quantikine ELISA Kit
The Quantikine Human I-TAC Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human I-TAC in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human I-TAC and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human I-TAC 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 I-TAC.

Recovery for Human CXCL11/I-TAC Quantikine ELISA Kit
The recovery of I-TAC spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 100 | 91-111 |
| EDTA Plasma (n=5) | 98 | 85-112 |
| Heparin Plasma (n=5) | 98 | 90-106 |
| Serum (n=5) | 106 | 93-117 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of I-TAC were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
