Biological Activity
Human IgG4 kappa
Human
PDCD1/PD-1/CD279
Ezabenlimab inhibits the interaction of PD-1 to PD-L1 and PD-L2 in CHO cells with IC90s of 4.14 nM and 3.98 nM, respectively; and inhibits the interaction of PD-1 to PD-L1 and PD-L2 in cynomolgus with IC90s of 5.61 nM and 7.54 nM, respectively[1].
Ezabenlimab increases IFN-γ secretion in primary human antigen-experienced CD3-positive T cells, with an EC50 value of 0.9 nM[1].
Ezabenlimab (200 nM) has synergistic effect with BI 754111, resulting in further increase of IFN-γ secretion[1].

Flow cytometric analysis of 1X106 10 ng/mL PMA and 1 μg/mL Ionomycin co-stimulated Jurkat cells(24h) labeling Ezabenlimab (HY-P99610, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 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 IgG4 kappa (HY-P99003, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
