Figure 3From: Kaliziri extract upregulates tyrosinase, TRP-1, TRP-2 and MITF expression in murine B16 melanoma cells Cytotoxicity of KZE in B16 melanoma cells. Effect of KZE on B16 cell viability. B16 cells were treated for 48 h with various concentrations of KZE (6.25-800 μg/ml) and cell viability was determined by the MTT reduction assay. Data are expressed as mean ± SD (n = 6).Back to article page
