Species of Origin
His Tag (C-term)
Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.
>95% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 7.16 kDa.
The protein migrates as 9-11 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to induce 3T3 cells proliferation. The ED₅₀ for this effect is < 1.0 ng/mL. The specific activity of recombinant human EGF is approximately >1.0 x 10⁶ IU/mg.
<0.1 EU per 1 μg of the protein by the LAL method.
Human epidermal Growth Factors (EGF) is a 6 kDa cytokine with 53 amino acid residues. EGF is mainly secreted from ectodermal cells, monocytes, kidney and duodenal glands. Upon binding to its receptor, EGFR, EGF acts to stimulate cell growth and proliferation of epithelial cells, play important roles in many developmental processes including accelerate tooth eruption, inhibits gastric acid secretion, and involve in wound healing.
Epidermal Growth Factors, Urogastrone, URG
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
