Product Summary
The Quantikine Porcine TNF-alpha Immunoassay is a 4.5 hour solid phase ELISA designed to measure porcine TNF-alpha in cell culture supernates, serum, and plasma samples. It contains E. coli-expressed recombinant porcine TNF-alpha and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately measure recombinant porcine TNF-alpha. Results obtained using natural porcine TNF-alpha show dose response curves that are 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 porcine TNF-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, six samples containing and/or spiked with various concentrations of porcine TNF-alpha in each matrix were diluted with the appropriate Calibrator Diluent and then assayed.
