Product Summary for Human GDF-15 Quantikine ELISA Kit
The Quantikine Human GDF-15 immunoassay is a 3.5 hour solid phase ELISA designed to measure GDF-15 in cell culture supernates, serum, plasma, and urine. It contains CHO cell-expressed recombinant human GDF-15 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural GDF-15 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 of naturally occurring GDF-15.

Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of GDF-15 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
