Gibco™ Human BTLA Fc Recombinant Protein, PeproTech®

Description

Recombinant Protein

PeproTech's CHO cell-derived Recombinant Human BTLA Fc is a glycosylated, disulfide-linked homodimer of 353-amino-acid-residues whose monomer consists of a 120-amino-acid portion of the extracellular domain fused to the 231-amino-acid length Fc portion of human IgG by two glycine residues. The calculated molecular weight of monomeric CHO cell-derived Recombinant Human BTLA Fc is 39.8 kDa; however, due to glycosylation, it migrates at an apparent molecular weight of approximately 50-55 kDa by SDS-PAGE analysis under reducing conditions. This product is shipped at ambient temperature. For storage, handling and reconstitution information, please see the lot-specific Certificate of Analysis

BTLA or B and T-lymphocyte attenuator is a member of the co-inhibitory receptors of the CD28 superfamily. BTLA is a lymphocyte inhibitory receptor which inhibits lymphocytes during immunes responses. BTLA is constitutively expressed on most CD4+ and CD8+ T cells and its expression progressively decreases upon T cell activation. It remains expressed on Th1 cells, but not Th2 cells. BTLA is a unique co-receptor that interacts with the tumor necrosis factor receptor superfamily member herpesvirus entry mediator (HVEM). This interation is an important pathway regulating lymphocyte activation and/or homeostasis in the immune response.
