Reconstitution Reconstitute the lyophilized recombinant Human Amphiregulin (HEK293-expressed) (rHuAmphiregulin) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Human Amphiregulin (HEK293-expressed) (rHuAmphiregulin) 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 Amphiregulin, an EGF receptor (EGFR) ligand, and essential for epithelial development in various organs. Amphiregulin is suggested to act as a protective factor in a liver injury model. In mice model with bleomycin-induced pneumopathy, Recombinant Human Amphiregulin improves the survival rate and suppresses the degrees of inflammation and fibrosis and the number of TUNEL-positive cells in lung tissues. Recombinant Human Amphiregulin treatment enhances the activation of Akt and Erk in lung epithelial cells[1]. |
