In Vitro
CTX-471 (5-500 nM) has bind affinity for recombinant human, cynomolgus macaque CD137 and mouse CD137 with Kd values of 50 nM, 61 nM and 748 nM, respectively[1].
CTX-471 binds to a unique epitope on CD137[1].
CTX-471 (0.1-100 nM; 1, 10 μg/mL; 3 days) increases IFN-y production by human T cells in an Fcy receptor-dependent (FcyR-dependent) manner in vitro[1].

Flow cytometric analysis of 1X106 10 ng/mL PMA and 1 μg/mL Ionomycin co-stimulated Jurkat cells(24h) with Retifanlimab (HY-P99941, 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). -
Loaded CTX-471 on ProA biosensor, can bind 4-1BB/TNFRSF9 Protein, Human (HEK293, His, HY-P70678) with an affinity constant of 1.840E-07 M as determined in BLI assay.
