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 that results in the induction of transcription factors NF-κB and AP-1. LIGHT (TNFSF14) and TNF-β (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-β. Recombinant Human HVEM-Fc Chimera is a 376 amino acid fusion protein that contains 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.

Purity > 95 % by SDS-PAGE and HPLC analyses. Biological Activity Fully biologically active when compared to standard. The biologically active as determined by its ability to inhibit TNF-beta -mediated cytotoxicity using murine L929 cells. Endotoxin < 0.1 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH7.4, with 3 % Trehalose. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. Shipping and Storage The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Cautions 1. Avoid repeated freeze-thaw cycles 2. For your safety and health, please wear lab coats and disposable gloves for operation. 3. For research use only.
