| Application: | EGF human has been used to check the action of EGF on lung epithelial NOS (nitric oxide synthase) in A549 cells (adenocarcinoma human alveolar basal epithelial cells). It has been used in the tumor sphere medium for culturing of brain tumor cells. |
| Biochem/physiol Actions: | EGF (epidermal growth factor) is a potent growth factor that stimulates the proliferation of various epidermal and epithelial cells. Additionally, EGF has been shown to inhibit gastric secretion, and to be involved in wound healing. It signals through a receptor known as c-erbB, which is a class I tyrosine kinase receptor. This receptor also binds with TGF (transforming growth factor)-α and VGF (vaccinia virus growth factor). Mutation in the EGF gene might be associated with risk of non-small cell lung adenocarcinoma. It is also involved in anaplastic thyroid cancer and renal hypomagnesemia. EGF controls cell differentiation and neurotrophic processes. |
| General description: | The gene EGF (epidermal growth factor) is mapped to human chromosome 4q25-27. The gene encodes for a large type I membrane–anchored precursor protein which is cleaved into pro-EGF for generation of peptide hormone EGF. The mRNA is expressed in the kidney, salivary gland, cerebrum and prostate. Recombinant human EGF is a 6.2kDa globular protein containing 53 amino acid residues including 3 intramolecular disulfide-bonds. |
| Physical form: | Lyophilized from 0.22 μm filtered solution in PBS. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization. |
| Reconstitution: | Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 μg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C. |
