Human T-cell immunoreceptor_x000D_with Ig and ITIM domains (TIGIT), also_x000D_known as V-set and immunoglobulin_x000D_domain-containing protein 9 (VSIG9), and_x000D_V-set and transmembrane domaincontaining_x000D_protein 3 (VSTM3), GenBank_x000D_Accession No. NM_173799, a.a. 22-141_x000D_fused to Fc region of human IgG1 and_x000D_enzymatically biotinylated using AviTag™_x000D_technology, expressed in a HEK293 cell_x000D_expression system. MW = 41.6 kDa_x000D_(monomer). This protein runs at a higher_x000D_MW by SDS-PAGE due to glycosylation.
