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 Bovine Tumor Necrosis Factor alpha (rBoTNF-α) to 100 μg/mL using ddH2O or PBS. Storage & Stability Lyophilized recombinant Bovine Tumor Necrosis Factor alpha (rBoTNF-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 Tumor Necrosis Factor alpha is a cytokine involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction. Bovine tumor necrosis factor-α alters luteal cell synthetic capacity and viability[1]. |
