Human CD155 / PVR Protein, Fc Tag

  • Synonym
  • Source
    Human CD155, Fc Tag (CD5-H5251) is expressed from human 293 cells (HEK293). It contains AA Trp 21 - Asn 343 (Accession # NP_006496.2).
    Predicted N-terminus: Trp 21
  • Molecular Characterization
    Online(Trp 21 - Asn 343) NP_006496.2

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 61.7 kDa. The protein migrates as 95-105 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Immobilized Human TIGIT, His Tag (Cat. No. TIT-H52H3) at 2 μg/mL (100 μL/well) can bind Human CD155, Fc Tag (Cat. No. CD5-H5251) with a linear range of 8-128 ng/mL (QC tested).

Human CD155, Fc TagHuman CD155, Fc Tag (Cat. No. CD5-H5251) ELISA bioactivity

Serial dilutions of Human TIGIT Neutralizing antibody were added into Human CD155, Fc Tag (Cat. No. CD5-H5251): Biotinylated Human TIGIT, Fc,Avitag (Cat. No. TIT-H82F1) binding reactions. The half maximal inhibitory concentration (IC50) is 0.06065 μg/mL (Routinely tested).

FACS assay shows that recombinant Biotinylated FACS

FACS assay shows that Human CD155, Fc Tag (Cat. No. CD5-H5251) can bind to 293T cell overexpressing human TIGIT. The concentration of CD155 is 1 μg/mL (Routinely tested).

FACS assay shows that recombinant Biotinylated FACS

FACS analysis shows that the binding of Human CD155, Fc Tag (Cat. No. CD5-H5251) 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 (Routinely tested).
