Product Summary
The Quantikine Human IL-1 alpha Immunoassay is a 3.5 or 4.5 hour solid phase ELISA designed to measure IL-1 alpha in cell culture supernates, serum, and plasma. It contains recombinant human IL-1 alpha and antibodies raised against recombinant human IL-1 alpha and has been shown to accurately quantitate the recombinant factor. Results obtained using natural IL-1 alpha showed linear curves that were parallel to the standard curves obtained using the E. coli-expressed Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-1 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
