Loaded Belrestotug on AHC2 biosensor, can bind TIGIT Protein, Human (120a.a, HEK293, His, HY-P70624) with an affinity constant of 6.401E-10 M as determined in BLI assay. -
Flow cytometric analysis of 1X106 FaDu cells with Belrestotug (HY-P990032, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. AF 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
