Product Summary
The Quantikine Mouse IL-4 Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse IL-4 levels in cell culture supernates and serum. It contains E. coli-expressed recombinant mouse IL-4 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse IL-4 accurately. Results obtained using natural mouse IL-4 showed dose curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse IL-4.
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
