The Human Epidermal growth factor (EGF) ELISA Kit is a sandwich immunoassay specifically designed and validated for the quantitative measurement of EGF in serum, plasma, cell culture supernates, or tissue homogenates. Human EGF is a single-chain polypeptide consisting of 53 amino acids. Physiologically in humans, EGF has different innate concentrations in various organs. EGF is implicated in the morphogenesis of teeth, brain, reproductive tracts, skin, and gastrointestinal tracts, in cardiovascular differentiation and function, epithelial regeneration, and corneal epithelia. EGF/EGFR signaling pathway regulates proliferation, migration, differentiation, and apoptosis in mammalian cells. Aberrations of the EGF/EGFR signaling pathway will lead to human cancer.
This assay employs the Sandwich-ELISA technique, in which eNOS in the samples or standards is sandwiched between pre-coated an anti-human CgA and Biotin-labeled eNOS antibody. The Ag-Ab-Ag immune complex is labeled with HRP-avidin and then develops a color reaction after the addition of the TMB substrate. The intensity of the color is positively correlated to the amount of eNOS in the sample. The kit has high sensitivity, excellent specificity, precision low than 10%, and good lot-to-lot consistency.
