From: Epanorin, a lichen secondary metabolite, inhibits proliferation of MCF-7 breast cancer cells
Sulforhodamine B proliferation assays. The inhibition of EP on cell proliferation was tested for normal human fibroblasts (b, c), a primary culture of menangioma (a) and the MCF-7 cell line (d). Cells were cultured for 48 h in the presence or absence of EP at concentrations from 14 to 98 μM. After quantifying proteins at each well by the sulforhodamine assay, the percentage of inhibition was calculated from the ratio of the signals with each tested concentration of EP and the cells grown in cell culture media. This is the result of a single experiment performed in triplicates
