Gene Information
human ... EPGN(255324)
General description
The precursor EPGN (epigen) is a transmembrane glycoprotein and is widely expressed in human tissues. The precursor is cleaved to give a soluble EGF (epidermal growth factor)-like domain.
Recombinant Human epigen, produced in Escherichia coli is a single, non-glycosylated, polypeptide chain containing 72 amino acids and having a molecular mass of 7.9kDa.

Biochem/physiol Actions
EPGN (epigen) is a ligand for EGFR (epidermal growth factor receptor). EPGN (epigen) belongs to the EGF family and enhances proliferation in keratinocytes.
Physical form
EPGN was lyophilized from 20 mM PBS buffer pH-7.4 containing 130 mM sodium chloride.
Preparation Note
Centrifuge the vial prior to opening. Avoid freeze-thaw cycles.
Reconstitute in sterile d-H2O not less than 100 μg/ml. For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA).
