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.

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 EGF spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=5) 98 88-111
Citrate Plasma (n=10) 104 89-115
EDTA Plasma (n=10) 100 80-111
Heparin Plasma (n=10) 96 79-108
Serum (n=10) 97 80-106
Urine (n=1) 102 97-108
To assess the linearity of the assay, samples were spiked with high concentrations of EGF in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: EGF
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.
