HVEM-Fc, Human, Recombinant

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 can act as a ldquo, receptor decoy rdquo, 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.

Determined by its ability to neutralize 0.25 ng/ml of hTNF beta, induced cytotoxicity on murine L929 cells. The expected ED 50 for this effect is 1.3-1.9 ug/ml of HVEM-Fc.

Verified by N-terminal and Mass Spectrometry analyses (when applicable).
