The LysoTracker® probes consist of a fluorophore linked to a weak base that is only partially protonated at neutral pH. This allows LysoTracker® probes to freely permeate cell membranes enabling them to label live cells. LysoTracker® probes are highly selective for acidic organelles, and unlike dinitrophenyl (DNP), LysoTracker® probes do not require use of a second antibody for detection.
LysoTracker® probes are available in a variety of fluorescent colors.
LysoTracker® Red DND-99
LysoTracker® Red DND-99 is a red-fluorescent dye for labeling and tracking acidic organelles in live cells.
Features of all LysoTracker® probes include:
• High selectivity for acidic organelles
• Good retention after aldehyde fixation
• Effective labeling of live cells at nanomolar concentrations
• Live cell imaging
• Excitation/Emission: 577/590 nm
