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.
Product Category	Recombinant Protein

Target	EGF
Synonyms	HOMG4; EGF; URG
Gene/Protein ID	P01133-1
Species	Human
Exact Sequence	Asn971-Arg1023
Molecular Weight	The protein has a predicted MW of 5.6 kDa same as Tris-Bis PAGE result.
Activity	Immobilized Human EGF, No Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human EGFR, hFc Tag with the EC50 of 0.82ug/ml determined by ELISA (QC Test). The affinity constant of 0.18 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	No Tag
Express System	E.coli
Purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU 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	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
