Human EGF Protein
Recombinant Human EGF Protein is expressed from HEK293 with hFc tag at the N-Terminus.It contains Asn971-Arg1023 [Accession | P01133-1].
The protein has a predicted MW of 32.52 kDa. Due to glycosylation, the protein migrates to 38-43 kDa based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
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.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human EGF on Bis-Tris 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 Biotinylated Human EGFR, His Tag at 1μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human EGF, hFc Tag with the EC50 of 4.1ng/ml determined by ELISA (QC Test).
Human EGFR, His Tag captured on CM5 Chip via anti-his antibody can bind Human EGF, hFc Tag with an affinity constant of 0.39 nM as determined in SPR assay (Biacore T200).
Measured in a cell proliferation assay using Balb/C 3T3 mouse embryonic fibroblast cells. The ED50 for this effect is typically 0.2 - 1.5 ng/mL.
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.
