|Description||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, CD+8 tumor infiltrating lymphocytes, granulocytes, and monocytes. LIGHT has the ability to active NFκB, to co-stimulate the activation of lymphocytes and to induce apoptosis in certain human tumor cells. Recombinant human LIGHT has a calculated mass of 19.3 kDa containing 177 amino acid residues. Due to glycosylation LIGHT migrates between 20.0-22.5 kDa by SDS-PAGE under non-reducing conditions.|
|BiologicalActivity||Determined by its cytotoxic effect on HT-29 cells (human colon adenocarcinoma cells) in the presence of human IFN-gamma.|
|Authenticity||Verified by N-terminal and Mass Spectrometry analyses (when applicable).|
|Endotoxin||Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg).|
|Protein Content||Verified by UV Spectroscopy and/or SDS-PAGE gel.|
|Precautions||Recombinant Human LIGHT is for research use only and not for use in diagnostic or therapeutic procedures.|
