產(chǎn)品規(guī)格:5μg/25μg/1mg
Synonyms | EPG, Epigen, PRO9904, ALGV3072, FLJ75542, EPGN, Epithelial mitogen. |
Introduction | 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. |
Description | 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. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | EPGN was lyophilized from 20mM PBS buffer pH-7.4 containing 130mM sodium chloride. |
Solubility | 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. |
Stability | Lyophilized Epigen although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution EPGN should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
Biological Activity | Determined by the dose-dependent stimulation of the proliferation of murine Balb/3T3 cells. The expected ED50 for this effect is 150-300ng/ml. |
Purity | Greater than 98.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
Amino acid sequence | AVTVTPPITA ADNIEGPI ALKFSHLCLE DHNSYCINGA CAFHHELEKA ICRCFTGYTG ERCEHLTLTS YA. |
Usage | ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
