Recombinant Human LIGHT

LIGHT is a type II transmemebrane protein and a member of the TNF cytokine family also referred to as TNFSF14 and it is identical with HVEM ligand. LIGHT is expressed in splenocytes, activated PBL, CD8+ tumor infiltrating lymphocytes, granulocytes and monocytes. LIGHT has the ability to activate NFkB, stimulate proliferation of lymphocytes, and induce apoptosis in certain human tumor cells. LIGHT binds to three receptors; the herpes virus entry mediator type A receptor (HEVM), LTbR and a decoy receptor (DcR3).¹

Lyophilized

The predicted molecular weight of Recombinant Human LIGHT is Mr 20.9 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 25 kDa.

20.9

This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
