Recombinant Human Epigen (CHO-expressed) 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。

Lyophilized after extensive dialysis against PBS, pH 7.4. Endotoxin Level
<0.2 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Human Epigen (CHO-expressed) (rHuEpigen) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability
Lyophilized recombinant Human Epigen (CHO-expressed) (rHuEpigen) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week 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 (CHO-expressed) 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]. |
