Recombinant Human EGF Protein (RP01030)

Overview

Product name	Recombinant Human EGF Protein
Catalog No.	RP01030
Description	Recombinant Human EGF Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Asn 971-Arg 1023) of human EGF (Accession #NP_001954.2) fused with hFc, 6×His tag at the C-terminus.
Bio-Activity	1.Measured by its ability to stimulate EGF Receptor autophosphorylation in A431 cells.1-10 ng/mL of Recombinant Human EGF can effectively enhance EGF Receptor autophosphorylation. 2.Measured by its binding ability in a functional ELISA. Immobilized Human EGFR at 5 μg/mL (100 μL/well) can bind Human EGF with a linear range of 7-25 ng/mL. 3.Measured in a cell proliferation assay using BALB/c 3T3 mouse embryonic fibroblasts. The ED₅₀ for this effect is typically 0.065-0.26 ng/mL, corresponding to a specific activity of 3.84×10⁶-1.54×10⁷units/mg.
Purity	> 90% by SDS-PAGE.
Endotoxin	< 0.1 EU/μg of the protein by LAL method.
Formulation	Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Species	Human
Calculated MW	33.01 kDa

Epidermal growth factor (EGF) is the founding member of the EGF family that also includes TGF-alpha, amphiregulin (AR), betacellulin (BTC), epiregulin (EPR), heparin binding EGF like growth factor (HB_x005f

Usage guide

Storage	Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Reconstitution	Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
