Biotinylated Human TIGIT Protein, Fc, Avitag™ (MALS verified)

T-cell immunoreceptor with Ig and ITIM domains (TIGIT) is also known as V-set and immunoglobulin domain-containing protein 9 (VSIG9), V-set and transmembrane domain-containing protein 3 (VSTM3), which belongs to single-pass type I membrane protein containing an immunoglobulin variable domain, a transmembrane domain and an immunoreceptor tyrosine-based inhibitory motif (ITIM) . TIGIT is expressed at low levels on peripheral memory and regulatory CD4+ T-cells and NK cells and is up-regulated following activation of these cells (at protein level) . TIGIT binds with high affinity to the poliovirus receptor (PVR) which causes increased secretion of IL10 and decreased secretion of IL12B and suppresses T-cell activation by promoting the generation of mature immunoregulatory dendritic cells.

Product Specifications

Background

Specifications

This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™) . The protein has a calculated MW of 41.3 kDa. The protein migrates as 45-55 kDa under reducing (R) condition, and 85-115 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
