Description
General description
Epidermal Growth Factor (EGF) is a polypeptide growth factor which stimulates the proliferation of a wide range of epidermal and epithelial cells. Human EGF is a 6.2 kDa protein containing 53 amino acid residues.
Product Source: E.coli
Application
For most in vitro applications, EGF exerts its biological activity in the concentration range of 0.5 to 25.0 ng/mL. Responding cells are (partial list): Epidermal mesothelial cells.
Physical form
Lyophilized from sterile filtered 10 mM Sodium Phosphate, pH 7.5, containing no additives.
Preparation Note
The lyophilized EGF, though stable at room temperature, is best stored desiccated at -20°C. Reconstitute with water to a concentration of 0.1 - 1 mg/mL. This solution can be diluted into other buffered solutions and stored at 4°C for 1 week or -20°C for future use. Reconstituted EGF should be maintained at -20°C in undiluted aliquots for up to one year.
Analysis Note
Specific Activity: Human EGF is fully biologically active when compared to standards.The ED50, as determined by its dose-dependent mitogenic activity on BALB/c 3T3 cells, is ≤ 0.1 ng/mL
