Figure Lengend Snippet: Correlation between GST activity and fluorescence intensity in various cancer cell lines. ( A ) Seven cancer cell lines (MKN45, HuH-28, HGC27, DLD1, CCK81, M7609, and NUGC-4) were incubated with DNAT-Me at 10 μM for 10 min and observed under fluorescence microscopy with excitation at 488 nm. Fluorescence intensity per cell in each cell line was quantitated using software provided by the manufacturer, as described in Materials and Methods. A primary normal adult human dermal fibroblast line (HDFa) was used as a negative control. ( B ) The cytosolic fraction was extracted from each cell line, and GST activity was measured using 1-chloro-2,4- dinitrobenzene and glutathione as substrates.
