- BIOLOGICAL ACTIVITY: Biological activity was determined by its ability to neutralize 0.25 ng/mL of hTNFB induced cytotoxicity on murine L929 cells. The expected ED50 for this effect is 1.3 - 1.9 μg/mL of HVEM - Fc.
Properties
- PURITY: Greater than 98% 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 HVEM-Fc recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted HVEM-Fc is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing HVEM-Fc 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.

Background
- HVEM belongs to the TNF Receptor superfamily of transmembrane proteins and plays a role in the activation of T-cells and other lymphocytes. It is expressed in various cells and tissues including spleen, thymus, lung, macrophages, and T-cells. HVEM activation induces a signaling cascade which results in induction of transcription factors NF-kappaB and AP-1. LIGHT (TNFSF14) and TNF-beta (TNFSF1) function as the ligands for HVEM, which can also bind specifically to herpes simplex virus glycoprotein D. Soluble HVEM, which tends to form disulfide-linked heterodimeric complexes in solution, can act as a "receptor decoy” resulting in inhibition of the activity of the HVEM ligands, LIGHT and TNF-beta. Recombinant human HVEM-Fc Chimera is a 376 amino acid fusion protein containing an N-terminal domain corresponding to the extracellular region of HVEM and a C-terminal domain corresponding to residues 102 to 330 of human IgG1.
