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]. |
