INTENDED USE

Pre-titrated Reagent Kit for human EGF contains calibrated EGF standards and pre-titrated capture and detection antibodies for quantitative measurement of human EGF in biological samples by enzyme-linked immunoassay (ELISA). An assay protocol is provided with the kit to use the reagents in 96-well ELISA format. It is recommended to dilute all reagents according to this manual. The lyophilized standards have been calibrated against WHO reference material to ensure accuracy and consistence of test results. The reagents can also be used with 384-well ELISA plate and optimized for use in other type of immunoassays.

Background

Epidermal growth factor (EGF), along with its receptor EGFR, plays an important role in cell proliferation, differentiation and survival. The binding of EGF to EGFR triggers the intrinsic tyrosine kinase activity of EGFR, activates signalling molecules and stimulates the synthesis of proteins and DNAs. EGF is crucial for maintaining mucosal lining in gastrointestinal duct and for healing of oral and gastroesophageal ulcers. EGF signalling is needed for cancer growth. Monoclonal antibodies that block EGFR have been applied for lung cancer and colon cancer treatment.
