Product Summary for Human BAFF/BLyS/TNFSF13B Quantikine ELISA Kit
The Quantikine Human BAFF/BLyS Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human BAFF/BLyS in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human BAFF/BLyS and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human BAFF/BLyS 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 BAFF.

Recovery for Human BAFF/BLyS/TNFSF13B Quantikine ELISA Kit
The recovery of BAFF/BLyS spiked to three different levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 96 | 90-103 |
| EDTA Plasma (n=4) | 94 | 84-101 |
| Heparin Plasma (n=4) | 94 | 89-107 |
| Serum (n=4) | 93 | 84-106 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of BAFF/BLyS were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
