Figure 2. Intracellular cathepsin activity was detected in HL60 cells using Magic Red®-(LR)2 cathepsin K fluorogenic substrate. Intracellular localization of the hydrolyzed fluorescent Magic Red® product was detected using a Nikon Eclipse E800 photomicroscope equipped with a 510-560 nm excitation filter and a 570-620 nm emission/barrier filter at 500X (A). Photo at right (B) shows the corresponding DIC image of the cells. Data courtesy of Dr. Brian Lee, ICT, 061202.
Figure 3. MCF-7 cells were stained with acridine orange for 30 minutes, washed twice in PBS (cells not stained with Magic Red®) and then analyzed by fluorescence microscopy at 400X using either 492 nm excitation with a 540-550 nm emission filter (A, lysosomes appear yellowish green), or 540 nm excitation with a long pass >640 nm barrier filter (B, lysosomes appear red). Data from the laboratory of Dr. Z. Darzynkiewicz (Brander Cancer Research Center Institute, New York City, NY).

Photomicroscope (Nikon Eclipse E800) analysis using a 460-500 nm excitation filter and a 505-560 nm emission/barrier filter set at 300X. Panel B shows the corresponding DIC image.
