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 Rhesus Macaque Tumor Necrosis Factor alpha (rRhTNF-α) to 100 μg/mL using ddH2O. Storage & Stability Lyophilized recombinant Rhesus Macaque Tumor Necrosis Factor alpha (rRhTNF-α) 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 TNF-α (Tumor Necrosis Factor alpha) is a cytokine involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction. TNF-α induces a model of preeclampsia in pregnant baboons (Papio hamadryas)[1]. TNF-α suppreses GnRH pulse generator activity at least partially through PG, but not CRH, dependent mechanisms[2]. |
