| Precautions | Recombinant Human EGF, 53 a.a. is for research use only and not for use in diagnostic or therapeutic procedures. |
| Epidermal growth factor (EGF) is a protein that stimulates cell growth and differentiation by binding to its receptor, EGFR. It was originally discovered in the submaxillary glands of mice and in human urine, and then has been found in many human tissues. EGF stimulates the proliferation of various epidermal and epithelial cells, inhibits gastric secretion, and involves in wound healing. Recombinant human EGF is a single non-glycosylated polypeptide chain containing 53 amino acids.，there are 3 intramolecular disulfide bonds in the EGF polypeptide chain and the molecular weight of EGF is 6.2kDa. |
