LysoTracker® Deep Red is a deep red-fluorescent dye for labeling and tracking acidic organelles in live cells.

Features of all LysoTracker® probes include:

• High selectivity for acidic organelles
• Effective labeling of live cells at nanomolar concentrations
• Live-cell imaging
• With excitation/emission of 647/668 nm, the same filter set can be used as used for Cy5 or MitoTracker® Deep Red

Simple, Highly Specific, One-Step Staining and Tracking of Acidic Organelles
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.
For Research Use Only. Not for use in diagnostic procedures.
