Epidermal growth factor (EGF) is a small protein that binds to receptors on the surface of cells and stimulates their division and proliferation. EGF is identical to urogastrone, which was isolated from urine, and first used as a drug in 1986. EGF also exists in nature as a component of both intact human saliva and parotid exocrine secretion.EGF (or Epidermal Growth Factor) is a peptide signaling molecule and the founding member of the EGF-family of proteins. It is present in high concentration in the human placenta and colostrum, and stimulates cell growth and differentiation.
What is egf: Epidermal growth factor (EGF) is a protein that stimulates cell growth. It is one of five polypeptide hormones which affect cell division and differentiation, the others being nerve growth factor (NGF), insulin-like growth factors I and II (IGF1, IGF2), and vascular endothelial growth factor (VEGF).A protein growth factor, epidermal growth factor (EGF) belongs to the EGF family and is involved in cellular differentiation and proliferation. It stimulates the growth of epithelial cells, summon and help various cell types develop into mature functioning tissue. EGF also plays a part in healing wounds and maintaining the health of skin, bladder lining(s), lung lining(s), stomach lining and salivary glands.
What is hplc test: HPLC, or High Performance Liquid Chromatography is one of the most widely used techniques for drug testing in formulations and biological fluids. Usually, the first step in HPLC method development is to review existing information given substantial research has already been published on this topic. Next, it is imperative to select a proper HPLC column that can provide a sharp peak with a reasonable retention time. In this step, a neat solution of the analyte is chromatographed using an appropriate column. There are countless choices of HPLC columns from different vendors, and the selection of an adequate column can itself be challenging. Afterward, we should select a suitable mobile phase for sound separation of analyte from impurities or endogenous material. Closer to the end, we deliberate over the detection technique for HPLC method development.

High-performance liquid chromatography (HPLC) is a popular analytical technique that is widely used in areas of chemistry and biology, including drug development and analysis. HPLC can be used to separate analytes from a mixture while measuring the concentration of each species present. In order to ensure accurate results and a reliable method, it is important to have an understanding of all aspects involved with developing and validating an HPLC method, including column selection, mobile phase choice and gradient programming. Ultimately, selecting the appropriate detection technique will increase the success rate of your assay.
