NucView\u00ae 405 Caspase-3 Substrate, 1 mM in DMSO, provides a convenient tool for detecting apoptosis in intact cells based on caspase-3\/7 activity using either confocal microscopy or flow cytometry. In contrast to other fluorogenic caspase substrates or fluorescent caspase inhibitor based (FLICA) assays, NucView\u00ae caspase-3 substrates can be used to detect caspase-3\/7 activity within individual intact cells without inhibiting apoptosis progression. NucView\u00ae substrates consist of a fluorogenic DNA dye coupled to the caspase-3\/7 DEVD recognition sequence. The substrate, which is initially non-fluorescent, penetrates the plasma membrane and enters the cytoplasm. In apoptotic cells, caspase-3\/7 cleaves the substrate, releasing the high-affinity DNA dye, which migrates to the cell nucleus and stains DNA with fluorescence. Thus, NucView caspase-3 substrates are bifunctional, allowing detection of caspase-3\/7 activity and visualization of morphological changes in the nucleus during apoptosis. The staining is also formaldehyde-fixable.\u00a0\u00a0NucView\u00ae 405 dye is excited by the 405 nm laser line for detection by confocal microscopy in the DAPI channel, or by flow cytometry in the Pacific Blue\u00ae channel. NucView\u00ae 405 is ideal for caspase-3 detection in multi-color applications for researchers who wish to reserve the green fluorescence channel for other detection reagents. Note: NucView\u00ae 405 signal may be difficult to observe using epifluorescence microscopy. Confocal microscopy using 405 nm laser excitation is recommended for imaging.\u00a0\u00a0NucView\u00ae 405 also is available at 1 mM in PBS for use in DMSO-sensitive cells. Biotium also offers green fluorescent NucView\u00ae 488 and orange fluorescent NucView\u00ae caspase-3 substrates.\u00a0\u00a0Pacific Blue is a registered trademark of Thermo Fisher Scientific.<\/p>\n
