Recombinant Human Epigen 是一种表皮生长因子,对只表达 ErbB-2 的细胞没有刺激作用,在表达 ErbB-1, 共表达 ErbB-2 和其他 ErbB 的细胞中,作为细胞分裂素能够促进细胞有丝分裂。 Synonyms rHuEpigen; Epithelial mitogen; EPG ; 重组人 Epigen 因子 Species HumanSource E. coli Accession Q6UW88 Gene ID 255324 Molecular Weight Approximately 8.1 kDa AA Sequence MAVTVTPPIT AQQADNIEGP IALKFSHLCL EDHNSYCING ACAFHHELEK AICRCFTGYT GERCEHLTLT SYA Biological Activity The ED50 is <1 μg/mL as measured by 3T3 cells, corresponding to a specific activity of >1 × 103 units/mg. Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Epigen (rHuEpigen) to 100 μg/mL using ddH2O. Storage & Stability Lyophilized recombinant Human Epigen (rHuEpigen) is stored at -20°C. After reconstitution, it is stable at 4°C for 2 weeks or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Recombinant Human Epigen is a EGF-like growth factor that does not stimulate cells singly expressing ErbB-2, but acts as a mitogen for cells expressing ErbB-1 and co-expressing ErbB-2 in combination with the other ErbBs, with potent mitogenic activity[1]. |
