Recombinant Murine Epidermal Growth FactorEGFHMGF (Human Milk Growth Factor)PGF (Prostatic Growth Factor)

EGF (Epidermal Growth Factor) is a family of growth factors that are derived from membrane-anchored precursors. The family is characterized by the presence of at least one “EGF-like domain” (characterized by the presence of three disulfide bonds, formed from 6 conserved cysteine residues) in their extracellular domain.EGF was originally discovered as an activity that induced early eyelid opening, incisor eruption, hair growth inhibition and stunting of growth when injected into newborn mice. Additionally, EGF has been shown to inhibit gastric secretion, is involved in wound healing and signals through a receptor known as c-erbB (a class I tyrosine kinase receptor).

Storage/Handling: This lyophilizedpreparation is stable at 2-8°C, but should be kept at -20°C for long termstorage. The reconstituted sample can be apportioned into working aliquots andstored at -80 °C for up to 6 months. Avoid repeated freeze/thaw cycles.

Reconstitution: The sample shouldbe briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitutein a siliconized tube using PBS that contains a 0.1% BSA to a concentration of0.1-1.0 mg/mL. Reconstituted solutions are stable for up to one week at 2-8°C.Stock solutions should be aliquoted and stored at -80°C. Further dilutionsshould be made in appropriate buffered solutions containing BSA or serum.
