Biological Activity
Human IgG4 kappa
Human
PDCD1/PD-1/CD279
Dostarlimab (10-10000 ng/mL) binds to native PD-1 receptor expressed on human and cynomolgus monkey CD3+ T cells in a dose-dependent manner[1].
Dostarlimab (0-375 nM; 48 h) increases IL-2 production with an EC50 of approximately 1 nM in a human CD4+ T-cell MLR assay, increases IL-2 production with an EC50 of approximately 0.1 nM in staphylococcal enterotoxin B (SEB)-stimulated PBMCs, enhances interferon (IFN)-γ release with an EC50 of approximately 0.5 nM[1].

Result:Resulted in great inhibition of tumor growth in an A549 lung cancer model (tumor growth inhibition [TGI] of 62% at termination). The antitumor activity was associated with a reduction in tumor-associated regulatory T cells and a trend toward increased tumor-infiltrating CD8+ T cells. Inhibited tumor growth of MDA-MB-436 breast cancer model (TGI of 53%).

Flow cytometric analysis of 1X106 10 ng/mL PMA and 1 μg/mL Ionomycin co-stimulated Jurkat cells(24h) with Dostarlimab (HY-P99345, 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).
