Recombinant Human HVEM-Fc/TNFRSF14

Description :
FAQ COA 已发表文献 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-B and AP-1. LIGHT (TNFSF14) and TNF- (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-. 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 Formulation Lyophilized from a 0.2 m 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.
