Product Description	Recombinant Human EGF Protein is expressed from E.coli without tag.It contains Asn971-Arg1023.
Product Background	The epidermal growth factor (EGF) family of peptides encodes several proteins that can function as growth factors. The EGF-like peptides, with the exception of proteins of the EGF-CFC subfamily, bind and activate tyrosine kinase receptors that belong to the erbB family.

Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 0.2 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

	Human EGFR, His Tag captured on CM5 Chip via anti-his antibody can bind Human EGF, No Tag with an affinity constant of 1.33 nM as determined in SPR assay (Biacore T200).
	Immobilized Human EGF, No Tag at 5ug/ml (100ul/well) on the plate. Dose response curve for Human EGFR, hFc Tag with the EC50 of 1.56ug/ml determined by ELISA (QC Test).
