Fig. 3From: An extract from the frass of swallowtail butterfly (Papilio machaon) larvae inhibits HCT116 colon cancer cell proliferation but not other cancer cell typesCell viability of HCT116 cells treated with fractions. (A, B) Fractions separated from Chl. ext. of O. javanica-fed larval frass (A) and their effect on HCT116 viability (B). (C, D) Fractions separated from Chl. ext. of F. vulgare-fed larval frass (C) and their effect on HCT116 viability (D). Cell viability was measured using the WST-8 assay. Error bars represent the mean ± SD from three biological replicatesBack to article page
