|Synonyms||TNF-alpha, Tumor necrosis factor ligand superfamily member 2, TNF-a, Cachectin, DIF, TNFA, TNFSF2|
|Description||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 . A type II transmembrane protein, TNF-α is further proteolytically processed to a soluble form . The trimeric active TNF-α then exerts its diverse biological properties including gapoptosis, inflammation, autoimmunity and cell proliferation by binding to TNF Receptor 1 and 2 .
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.
|Biological Activity||ED50<0.01ng/ml, measured by cytotoxicity assay using L929 cells, corresponding to a specific activity of >1 x 108units/mg.|
