200μg of α-CD8 (clone 2.43, BioXCell), α-CD4 (clone GK1.5, BioXCell), α-PD-1 (clone RMP1–14, BioXCell), or respective isotype controls were administered to mice via intraperitoneal injection on days 5, 7, 9, and 11 post-initial tumor challenge. NK cell depletion experiments followed the same dosing protocol, using 250μg of α-NK1.1 (clone PK136, BioXCell). CLEC9A blocking experiments followed the same dosing protocol, using 400μg of α-CLEC9A (clone 7H11, BioXCell) or isotype control, as described (28 (link)).
