From: Catechin hydrate suppresses MCF-7 proliferation through TP53/Caspase-mediated apoptosis
TUNEL assay (microscopic) after 48 hours incubation of MCF-7 against catechine treatment. A, B and C are untreated control; D, E and F treated with 150 μg/mL of catechine; G, H and I treated with 300 μg/mL of catechine. Red fluorescence is due to Propedium Iodide staining and observed under green filter while green fluorescence is due to FITC staining and observed under blue filter.
