Product Summary

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

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
