TNF beta Recombinant Protein, Prosci

Supplier: Prosci
Tumor Necrosis Factor beta (TNF- beta ) is a secreted protein belonging to the tumor necrosis factor family. TNF- beta binds to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR and TNFRSF14/HVEM in homotrimeric form, binds to TNFRSF3/LTBR in heterotrimeric form with LTB. TNF- beta forms heterotrimers with lymphotoxin-beta, which anchors TNF- beta to the cell surface. TNF- beta mediates the inflammatory, immunostimulatory, and antiviral response, involves in the formation of second lymphoid organs during development, has a role in apoptosis. TNF- beta is produced by lymphocytes and cytotoxic for a variety of tumor cells in vitro and in vivo.

This recombinant protein can be used for biological assays. For research use only.
