Product Summary for Human Follistatin Quantikine ELISA Kit
The Quantikine Human Follistatin Immunoassay is a 5.5 hour solid-phase ELISA designed to measure human Follistatin (FS288, FS300, and FS315) in follicular fluid, cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant human Follistatin and antibodies raised against the recombinant factor. It has been shown to accurately quantitate recombinant human Follistatin. Results obtained using natural Follistatin 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 Follistatin.

Recovery for Human Follistatin Quantikine ELISA Kit
The recovery of Follistatin spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 97 | 91-107 |
| EDTA Plasma (n=5) | 96 | 87-102 |
| Serum (n=5) | 95 | 87-104 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Follistatin were diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
