Lyophilized recombinant rat Tumor Necrosis Factor-Alpha (rrTNF-Alpha) remains stable up to 6 months at -80 °C from date of receipt. Upon reconstitution, rrTNF-Alpha should be stable up to 2 weeks at 4 °C or up to 3 months at -20 °C.
Tumor Necrosis Factor-Alpha (TNF-Alpha) also known as Cachectin and TNFSF1A, plays a major role in growth regulation, differentiation, inflammation, viral replication, tumorigenesis, and autoimmune diseases, and in viral, bacterial, fungal, and parasitic infections. Besides inducing hemorrhagic necrosis of tumors, TNF has been found to be involved in tumorigenesis, tumor metastasis, viral replication, septic shock, fever, inflammation, and autoimmune diseases including Crohn's disease, and rheumatoid arthritis as well as graft-versus-host disease.Recombinant rat Tumor Necrosis Factor-Alpha (rrTNF-Alpha) produced in P. pastoris is a glycosylated polypeptide chain containing 157 amino acids. A fully biologically active molecule, rrTNF-Alpha has a molecular mass of 17.4 kDa analyzed by reducing SDS-PAGE.
