Human TIGIT (T-cell immunoreceptor with Ig and ITIM domains) is also known as VSIG9, VSTM3. TIGIT protein dimer (CSP-24028) and contains a TIGIT extracellular domain (amino acids Met22-Phe141, UniProt# Q495A1) with a homodimer Fc tag at the C-terminus. This protein is expressed in HEK293 cells. The TIGIT-Fc dimer protein is bioactive and can bind to Nectin-4. It also binds to TIGIT-specific antibodies. This TIGIT dimer can be used as an antigen for in vitro assays and antibody screening, targeting more conformations epitopes.

SDS PAGE Molecular Weight: The migration range of the dimer under non-reducing condition is 85-150 kDa on SDS PAGE.
Protein Construct: TIGIT protein dimer contains a TIGIT extracellular domainwith a homodimer Fc tag at the C-terminus.
Background and Alternate Names
Human TIGIT (T-cell immunoreceptor with Ig and ITIM domains) is also known as VSIG9 (V-set and immunoglobulin domain-containing protein 9), VSTM3 (V-set and transmembrane domain-containing protein 3). TIGIT is a type I membrane protein containing an immunoglobulin variable (Ig-V) domain, a transmembrane domain and cytoplasmic domain. TIGIT is an immune receptor present on peripheral memory and regulatory CD4+ T cells and natural killer (NK) cells. TIGIT binds to CD155 (the poliovirus receptor, PVR) with high affinity and binds to CD112 (PVRL2) with lower affinity. Nectin-4 is also a ligand for TIGIT.
