Sharing 79% sequence identity with human Tumor Necrosis Factor-alpha (hTNF-α), mouse Tumor Necrosis Factor-alpha (mTNF-α) is a cytokine mainly expressed by immune cells [1]. A type II transmembrane protein, TNF-α is further proteolytically processed to a soluble form [2]. The trimeric active TNF-α[3] then exerts its diverse biological properties including gapoptosis, inflammation, autoimmunity and cell proliferation by binding to TNF Receptor 1 and 2 [4]. Recombinant mouse Tumor Necrosis Factor-alpha (rmTNF-α) produced in P.pastoris is a fully biologically active polypeptide chain of 152 amino acids with a molecular mass of 17 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
Lyophilized recombinant mouse Tumor Necrosis Factor-alpha (rmTNF-α) remains stable up to 6 months at -80°C from date of receipt. Upon reconstitution, rmTNF-αshould be stable up to 1 week at 4°C or up to 2 months at -20°C.
