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

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