SW480, SW620, HCT116, DLD1, LOVO, HT29, HEK293, and B16 cell lines were obtained from the ATCC and recently been authenticated by STR profiling. The SW480 cell line was cultured in
RPMI 1640 (Corning) supplemented with 10% FBS (PAN, P30-3302), and the SW620, HCT116, DLD1, LOVO, HT29, HEK293 as well as B16 cell lines were cultured in
DMEM (Corning) supplemented with 10% FBS. These cell lines were cultured in a 37 °C incubator with 5% (v/v) CO
2.
