Description

Epidermal growth factor (EGF) is a protein that stimulates cell growth and differentiation by binding to its receptor, EGFR. Human EGF is 6-kDa[5] and has 53 amino acid residues and three intramolecular disulfide bonds.
EGF was originally described as a secreted peptide found in the submaxillary glands of mice and in human urine. EGF has since been found in many human tissues, including platelets,submandibular gland (submaxillary gland), and parotid gland.Initially, human EGF was known as urogastrone.In humans, EGF has 53 amino acids (sequence NSDSECPLSHDGYCLHDGVCMYIEALDKYACNCVVGYIGERCQYRDLKWWELR),with a molecular mass of around 6 kDa. It contains three disulfide bridges (Cys6-Cys20, Cys14-Cys31, Cys33-Cys42).EGF, via binding to its cognate receptor, results in cellular proliferation, differentiation, and survival.Salivary EGF, which seems to be regulated by dietary inorganic iodine, also plays an important physiological role in the maintenance of oro-esophageal and gastric tissue integrity. The biological effects of salivary EGF include healing of oral and gastroesophageal ulcers, inhibition of gastric acid secretion, stimulation of DNA synthesis as well as mucosal protection from intraluminal injurious factors such as gastric acid, bile acids, pepsin, and trypsin and to physical, chemical and bacterial agents

The GENLISA Human Vascular Endothelial Cell Growth Factor (VEGF) ELISA includes features like:

Specificity

This assay recognises both the recombinant and natural protein for Vascular Endothelial Cell Growth Factor (VEGF)

Principle Of Assay

This ELISA is a sandwich immunoassay . Antibodies are coated on 96 well plates. The antigen protein present in sample and standard respectively bind to the coated wells. The wells are washed and an antibody:HRP Conjugate is added which binds to the bound complex in the well. Washing is performed to remove any unbound material. TMB substrate is added and the enzyme reaction is stopped by dispensing of stop solution into the wells. The optical density (OD) of the solution at 450 nm is directly proportional to the amount of antigen protein present in the standard or samples.

Detection Method

Colorimetric, Absorbance measured at 450nm

Conjugate-Enzyme Reaction

Uses stable HRP Enzyme Conjugate with (single component) TMB Chromogenic Substrate for color development.

Quality Certification

Validated as per KRISHGEN's Quality Program. GOLD PLUS (GOLD+) validation done. The kit is calibrated against NIBSC calibrator.
