EPG, Epigen, PRO9904, ALGV3072, FLJ75542, EPGN, Epithelial mitogen.
EPGN is an EGF-related polypeptide growth factor that signals through the ErbB receptor-1. EPGN is produced in numerous tissues, including the testis, liver, heart and in certain tumor cells. EPGN is mitogenic for fibroblasts and epithelial cells. Human EPGN is originally synthesized as a glycosylated 14.7 kDa transmembrane precursor protein, which is processed by proteolytic cleavage to produce a mature soluble sequence.
Epigen Recombinant Human produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 72 amino acids and having a molecular mass of 7.9 kDa.
Epigen is purified by proprietary chromatographic techniques.
Sterile Filtered White lyophilized (freeze-dried) powder.
EPGN was lyophilized from 20mM PBS buffer pH-7.4 containing 130mM sodium chloride.
It is recommended to reconstitute the lyophilized Epigen in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Epigen although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution EPGN should be stored at 4C between 2-7 days and for future use below -18C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
