LIGHT belongs to the TNF family of ligands, and can signal through the herpes virus entry mediator type A receptor (HVEM, TNFRSF14), LTβR, or bind to a decoy receptor, DcR3. It is expressed in splenocytes, activated PBL, CD8+ tumor infiltrating lymphocytes, granulocytes, and monocytes. LIGHT has the ability to active NF-κB, to co-stimulate the activation of lymphocytes and to induce apoptosis in certain human tumor cells. Recombinant Murine LIGHT is a 20.1 kDa protein containing 183 amino acid residues, comprising the TNF-homologous region of the LIGHT extracellular domain.
Amino Acid Sequence
Determined by its cytotoxic effecton HT-29 cells (human colon adenocarcinoma cells) in the presence of human IFN-γ.
Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at-20°C to –80°C.
