Product Summary

The Quantikine Human Thrombospondin-1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Thrombospondin-1 in cell culture supernates, serum, plasma, saliva, and human milk. It contains NS0-expressed recombinant human Thrombospondin-1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Thrombospondin-1 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 Thrombospondin-1.

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

Recovery

The recovery of Thrombospondin-1 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 95 86-101
Platelet-poor EDTA Plasma (n=4) 94 89-99
Platelet-poor Heparin Plasma (n=4) 93 87-104

Linearity

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