Weitere Details:
Quantitatively monitor intracellular cathepsin B activity over time in vitro. The Magic Red® substrate fluoresces red upon cleavage by active cathepsin enzymes. The signal can be analyzed using fluorescence microscopy or a fluorescence plate reader., ICT
Immunogen:
Cathepsin B

Figure 2. MCF-7 cells were stained with acridine orange for 30 minutes, then 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).
Figure 3. Jurkat cells stained with acridine orange in PBS for 60 minutes at 37°C show orange lysosomal staining (A). 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.

Figure 4. Intracellular cathepsin-B activity detected in Jurkat cells using our MR-(RR)2 cathepsin-B fluorogenic substrate. Intracellular localization of the hydrolyzed fluorescent Magic Red® product was detected using a Nikon Eclipse E800 photomicroscope fitted with 510-560 nm excitation and 570-620 nm emission/barrier filters at 500X (A). The corresponding DIC image is shown in (B). Data courtesy of Dr. Brian Lee, ICT, 061202.
