Chromium release assay utilizing a range of PMN (effectors) against various tumor targets. Purified splenic PMN from treated mouse groups (n=3) were used in a 51Cr cytotoxicity assay. Tumor targets consisted of KPC (pancreatic cancer), 4T1 (breast cancer), and B16F10 (melanoma) which were co-incubated directly with effectors at indicated E:T ratios. Each E:T ratio with specific tumor targets were done in triplicate. Percent lysis within the PEGPH20/shIDO-ST group was compared to the PEGPH20/shScr-ST treated group at each E:T ratio using Student's t test. Data shown is representative of multiple experiments.
