Human EGF Protein

产品信息(Product Info)

Recombinant Human EGF Protein is expressed from E.coli without tag. It contains Asn971-Arg1023.[Accession | P01133-1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 5.6 kDa same as Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.


Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


-20 to -80°C for 12 months as supplied from date of receipt.
-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Human EGF on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


The purity of Human EGF is greater than 95% as determined by SEC-HPLC.


Immobilized Human EGF, No Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Human EGFR, hFc Tag with the EC50 of 0.82μg/ml determined by ELISA (QC Test).

SPR Data

Human EGFR, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human EGF, No Tag with an affinity constant of 0.18 nM as determined in SPR assay (Biacore T200).

Cell Based Assay

Measured in a cell proliferation assay using Balb/C 3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 0.5-1 ng/mL (QC Test).


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.
