Product Summary

The Quantikine Human FGF-19 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human FGF-19 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human FGF-19 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human FGF-19 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 FGF-19.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

	Intra-Assay Precision			Inter-Assay Precision
Sample	1	2	3	1	2	3
n	20	20	20	40	40	40
Mean	113	346	689	119	349	700
Standard Deviation	7.26	15.7	24.8	6.46	19.3	31.7
CV%	6.4	4.5	3.6	5.5	5.5	4.5

Recovery

The recovery of FGF-19 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type	Average % Recovery	Range %
Cell Culture Media (n=4)	104	93-109
EDTA Plasma (n=4)	94	85-101
Heparin Plasma (n=4)	92	89-95
Serum (n=4)	95	88-100

Linearity

To assess the linearity of the assay, samples containing or spiked with high concentrations of FGF-19 were serially diluted with the Calibrator Diluent to produce samples with values within the dynamic range of the assay.
