Canine TIGIT Protein, His Tag

  • Synonym
  • Source
    Canine TIGIT, His Tag (TIT-C52H7) is expressed from human 293 cells (HEK293). It contains AA Phe 17 - Pro 208 (Accession # F1PKJ0-1).
    Predicted N-terminus: Phe 17
  • Molecular Characterization
    Online(Phe 17 - Pro 208) F1PKJ0-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 23.1 kDa. The protein migrates as 25-33 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Canine TIGIT, His TagCanine TIGIT, His Tag (Cat. No. TIT-C52H7) ELISA bioactivity

Immobilized Canine TIGIT, His Tag (Cat. No. TIT-C52H7) at 5 μg/mL (100 μL/well) can bind Human CD155, mouse IgG2a Fc tag, low endotoxin (Cat. No. CD5-H5254) with a linear range of 0.01-0.313 μg/mL (QC tested).


Loaded Human CD155, Fc Tag (Cat. No. CD5-H5251) on Protein A Biosensor, can bind Canine TIGIT, His Tag (Cat. No. TIT-C52H7) with an affinity constant of 5 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

  • Background
    TIGIT (also called T cell immunoreceptor with Ig and ITIM domains) is one newly discovered immune receptor on some percentage of T cells and Natural Killer Cells(NK). It is also identified as WUCAM and Vstm3. TIGIT could bind to CD155(PVR) on dendritic cells(DCs), macrophages, etc. with high affinity, and also to CD112(PVRL2) with lower affinity. TIGIT expressing CD8+ T cells has been shown to be expanded and associated with clinical markers of HIV disease progression in a diverse group of HIV infected individuals. TIGIT and PD-1 has been shown to be over expressed on tumor antigen-sepcific (TA-specific) CD8+ T cells and CD8+ tumor infiltrating lymphocytes (TILs) from individuals with melanoma. Blockade of TIGIT and PD-1 led to increased cell proliferation, cytokine production, and degranulation of TA-specific CD8+ T cells and TIL CD8+ T cells.
