The Quantikine Mouse EGF Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse EGF in cell culture supernates, tissue homogenates, serum, plasma, and urine. It contains E. coli-expressed recombinant mouse EGF and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse EGF 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 naturally occurring mouse EGF.
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
The recovery of mouse EGF spiked to three levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Supernates (n=4)
EDTA Plasma (n=4)
Heparin Plasma (n=4)
Tissue Homogenates (n=3)
To assess the linearity of the assay, samples spiked with or containing mouse EGF in each matrix were diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
EGF (Epidermal Growth Factor) is expressed as a transmembrane protein that is proteolytically cleaved to generate soluble forms. It signals through EGF R/ErbB1 which heterodimerizes with ErbB2, ErbB3, or ErbB4 and can also associate with PDGF R beta and HGF R/c-MET. During development, EGF regulates thymocyte differentiation, neuroglia production, and adipocyte maturation. In the adult, EGF plays a role in mammary gland lactogenesis, fibroblast mitosis, dissociation of the extracellular matrix, and cell migration.
Refer to the product for complete assay procedure.
Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
Prepare all reagents, standard dilutions, and samples as directed in the product insert.
Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
