TNF B Human, Sf9

Lymphotoxin-alpha, LT-alpha, TNF-beta, Tumor necrosis factor ligand superfamily member 1, LTA, LT, TNFB, TNFSF1.

Lymphotoxin alpha, a member of the tumor necrosis factor family, is a cytokine produced by lymphocytes. LTA is highly inducible, secreted, and exists as homotrimeric molecule. LTA forms heterotrimers with lymphotoxin-beta which anchors lymphotoxin-alpha to the cell surface. LTA mediates a large variety of inflammatory, immunostimulatory, and antiviral responses. LTA is also involved in the formation of secondary lymphoid organs during development and plays a role in apoptosis.

Tumor Necrosis Factor-beta Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 180 amino acids (35-205a.a.) and having a molecular mass of 19.7kDa (Molecular size on SDS-PAGE will appear at approximately 18-28kDa).
TNFB is fused with a 6 amino acids His tag at C-Terminus and purified by proprietary chromatographic techniques.
