Product Summary
The Quantikine® HS Human TNF-alpha Immunoassay is a 4.0 hour solid phase ELISA designed to measure human TNF-alpha in serum and plasma. It contains E. coli-derived recombinant human TNF-alpha and antibodies raised against the recombinant factor. It has been shown to accurately quantitate recombinant human TNF-alpha. Results obtained with natural human TNF-alpha samples 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 human TNF-alpha.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components
Serum, EDTA Plasma, Heparin Plasma
