Epidermal Growth Factor (EGF) 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. EGF signals through a receptor known as c-erbB, which is a class I tyrosine kinase receptor. This receptor also binds with TGF-alpha and VGF (vaccinia virus growth factor). Recombinant murine EGF is a 6.0 kDa globular protein containing 53 amino acid residues, including 3 intramolecular disulfide-bonds.
Mouse Egf expressed in E.coli
CAT# CSC-CTK0661-500 (500 μg); CAT# CSC-CTK0661-2500 (2.5 mg)
Greater than 97% as determined by SDS-PAGE and HPLC analysis.
The ED50 was determined by a cell proliferation assay using BALB/c 3T3 cells is 1 x 10^7 units/mg.
Less than 1 EU/μg.
Lyophilized from a sterile-filtered solution in 1XPBS (pH 7.4).
Please centrifuge product briefly before opening the vial. Reconstitute in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized powder, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted EGF should be used immediately or stored in undiluted working aliquots at -20°C. Avoid repeated freeze / thaw cycles.
