表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Biotinylated Mouse TIGIT Protein, Fc,Avitag (TIT-M82F3) is expressed from human 293 cells (HEK293). It contains AA Gly 26 - Thr 143 (Accession # A0A0B4J1G6-1).

Predicted N-terminus: Gly 26

蛋白結(jié)構(gòu)（Molecular Characterization）

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 41.1 kDa. The protein migrates as 48-55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

標(biāo)記（Labeling）

Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白標(biāo)記度（Protein Ratio）

Passed as determined by the HABA assay / binding ELISA.

純度（Purity）

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制劑（Formulation）

背景介紹

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.
