Recombinant EGF (Epidermal growth factor), Human

Specifications

Product Data
Species	Human
Expression Host	E. coli
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) MNSDSECPLSHDGYCLHDGVCMYIEALDKYACNCVVGYIGERCQYRDLKWWELR with polyhistidine tag at the C-terminus
Tag	His Tag (C-term)
Predicted MW	The protein has a calculated MW of 7.16 kDa. The protein migrates as 9-11 kDa under reducing condition (SDS-PAGE analysis).
Purity	>95% as determined by SDS-PAGE.
Buffer	The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 8.0.
Applications	Cell culture
Storage	Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
Bioactivity	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.
Endotoxin	<0.1 EU per 1 μg of the protein by the LAL method.
Reference Data
UniProt ID	P01133
Synonyms	Urogastrone, URG
Summary	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.
