Reconstitute the lyophilized recombinant Murine Tumor Necrosis Factor-alpha/TNFSF2 (rMuTNF-α/TNFSF2) to 100 µg/mL using ddH2O or PBS. Storage & Stability
Lyophilized recombinant Murine Tumor Necrosis Factor-alpha/TNFSF2 (rMuTNF-α/TNFSF2) 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 α (TNF-α, also known as cachectin) is a strong pro-inflammatory cytokine playing an important role in the immune system during inflammation, cell proliferation, differentiation and apoptosis. TNF-α is type II transmembrane protein that can be expressed in both membrane-bound and secreted forms. Receptors for TNF-a are part of TNF receptor (TNFR) superfamily, with characteristic intracellular segment, a transmembrane domain, and an extracellular ligand-binding domain. They are type I transmembrane glycoproteins characterized by a cysteinerich motif (up to 40 aminoacids) repeated 2-6 times in the extracellular N-terminal domain[1]. |
