Product Summary

The Quantikine Human SDF-1 alpha Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human SDF-1 alpha in cell culture supernates and platelet-poor plasma. It contains E. coli-expressed recombinant human SDF-1 alpha and antibodies raised against the recombinant factor. It has been shown to accurately quantitate recombinant human SDF-1 alpha. Results obtained using natural SDF-1 alpha 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 SDF-1 alpha.

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

Cell Culture Supernates, EDTA Plasma, Platelet-poor Heparin Plasma

	Intra-Assay Precision			Inter-Assay Precision
Sample	1	2	3	1	2	3
n	20	20	20	40	40	40
Mean	491	1700	3420	544	1600	3150
Standard Deviation	19	58	115	73	150	257

Recovery

The recovery of SDF-1 alpha 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)	101	95-108
Platelet-poor EDTA Plasma (n=5)	97	90-107
Platelet-poor Heparin Plasma (n=5)	97	90-104

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of SDF-1 alpha were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
