Viability of SW480 colon cancer cells after treatment with limonoids was measured by the MTT method. Approximately 10*10^3 cells/well were plated into a 96-well. After 24 h of growth, media was replaced along with compounds at concentrations ranging from 6.25 to 100 uM. After 24, 48, and 72 h, MTT solutionwas added to each well and incubated at 37 C for 2 h.
