Recombinant Human LTA

• Description:

  TNF-beta is a potent mediator of inflammatory and immune responses. It belongs to the TNF family of ligands and signals through TNFR1 and TNFR2. TNF-beta is produced by activated T and B lymphocytes, and has similar activities to TNF-alpha. Like TNF-alpha, TNF-beta is involved in the regulation of various biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, coagulation, and neurotransmission. TNF-beta is secreted as a soluble polypeptide, but can form heterotrimers with lymphotoxin-beta, which effectively anchors the TNF-beta to the cell surface. TNF-beta is cytotoxic to a wide range of tumor cells.

• CAS Number:

  9000-83-3

• Gene Name:

  LTA

• Gene Aliases:

  Tumor necrosis factor ligand superfamily member 1, TNFSF1, Lymphotoxin-alpha, LT-alpha, LTA
  Recombinant Human Tumor Necrosis Factor Beta (LTA)

• Gene ID:

  4049

• Accession Number:

  P01374

• Organism:

  Human

• Source:

  E. coli

• Concentration:

  <1.0 EU/μg of recombinant protein as determined by the LAL method.

• Purity:

  >95% as determined by SDS-PAGE

• Solubility:

  A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

• Function:

  The ED(50) was measured in a cytotoxicity assay using mouse L929 cells in the presence of the metabolic inhibitor actinomycin, and was determined to be less than 0.1 ng/mL.

• Molecular Weight:

  19

• Shipping Conditions:

  Ambient Temperature

• Storage Conditions:

  The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

• Appearance:

  Lyophilized Powder

• Formulation:

  TNF-beta is presented as a 0.2 μm filtered PBS solution pH 7.5.
