In vivo depletion of PMN-MDSCs
To assess the effect of depleting PMN-MDSCs, mice were administered
intraperitoneally with 400𝜇g anti-Ly6G antibodies per mouse each time
(1A8, Bio X cell) or rat IgG2a isotype (Bio X cell) control antibodies
on day 32, 34, 36, 38, 40 after first immunization. And mice were
sacrificed on day 42.
