Greater than 95% by SDS-PAGE gel and HPLC analyses.
Endotoxin level is less than 0.1 ng per μg (1EU/μg).
PHYSICAL STATE:
Lyophilized
STORAGE CONDITIONS:
The lyophilized LIGHT recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted LIGHT is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing LIGHT recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
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.
