Figure 1From: Chloroquine treatment of ARPE-19 cells leads to lysosome dilation and intracellular lipid accumulation: possible implications of lysosomal dysfunction in macular degenerationCell Viability Assay. MTT assay shows chloroquine toxicity is both time and dose dependent. Chloroquine concentrations of 10-30 Ī¼g/ml (p < 0.05) do not significantly affect cell viability.Back to article page
