Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at -20°C or -80°C. Avoid freeze / thaw cycle.

    pH: 7.50
    Constituents: 0.61% Tris, 0.75% Glycine, 5% Trehalose, L-Arginine, Sodium chloride

    Lyophilized from 0.22 µm filtered solution.
    5-10% trehalose is commonly used for freeze drying, and after reconstitution, the trehalose is mostly about 3-5%

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • Reconstitution
    It is recommended to reconstitute the lyophilized protein in sterile deionized water to a final concentration of 1 mg/mL. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

  • Function

    Mediates NK cell adhesion and triggers NK cell effector functions. Binds two different NK cell receptors: CD96 and CD226. These interactions accumulates at the cell-cell contact site, leading to the formation of a mature immunological synapse between NK cell and target cell. This may trigger adhesion and secretion of lytic granules and IFN-gamma and activate cytoxicity of activated NK cells. May also promote NK cell-target cell modular exchange, and PVR transfer to the NK cell. This transfer is more important in some tumor cells expressing a lot of PVR, and may trigger fratricide NK cell activation, providing tumors with a mechanism of immunoevasion. Plays a role in mediating tumor cell invasion and migration. Serves as a receptor for poliovirus attachment to target cells. May play a role in axonal transport of poliovirus, by targeting virion-PVR-containing endocytic vesicles to the microtubular network through interaction with DYNLT1. This interaction would drive the virus-containing vesicle to the axonal retrograde transport.

  • Information by UniProt


  • FACS analysis shows that the binding of Human CD155, Fc Tag to 293T overexpressing TIGIT was inhibited by increasing concentration of neutralizing Anti-Human TIGIT MAb. The concentration of CD155 used is 1 µg/ml. The IC50 is 0.09422 µg/ml.
  • FACS assay shows that recombinant Human CD155, Fc Tag can bind to 293T cell overexpressing human TIGIT. The concentration of CD155 is 1 µg/ml.
  • Immobilized Human CD155, Fc Tag at 5 µg/mL (100 µL/well) can bind Biotinylated Human TIGIT, His Tag with a linear range of 5-78 ng/mL.
  • SDS-PAGE analysis of reduced ab220561 stained overnight with Coomassie Blue.

    The protein migrates as 95-105 kDa on a SDS-PAGE gel under reducing conditions due to glycosylation.
