Product Summary
The Quantikine Canine IFN-gamma Immunoassay is a 4 hour solid-phase ELISA designed to measure canine IFN-gamma in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant canine IFN-gamma and antibodies raised against the recombinant factor. Results obtained for naturally occurring canine IFN-gamma 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 canine IFN-gamma.
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 separate assays to assess inter-assay precision
