Descripción general

Lipophilic carbocyanine dyes are widely used for labeling neurons in tissues by retrograde labeling, and to label membranes in a wide variety of cell types. The dyes are weakly fluorescent in aqueous phase, but become highly fluorescent in lipid bilayers. Staining is highly stable with low toxicity and very little dye transfer in between cells, making the dyes suitable for long-term cell labeling and tracking studies. When live cells are stained, the dyes label plasma membranes and also are taken up into endocytic compartments. Cells can be fixed either before or after staining, although permeabilization affects the staining pattern.

Unlike PKH dyes, BioTracker Cytoplasmic Membrane Dyes do not require a complicated hypoosmotic labeling protocol. They are ready-to-use dye delivery solutions that can be added directly to normal culture media to label suspended or adherent cells in culture.

NIR Cytoplasmic Membrane Dyes are novel near-infrared carbocyanine dyes for labeling the cytoplasmic membranes of living cells. Due to their long emission wavelengths, near-infrared cell membrane stains can be used to label cells for near-infrared small animal imaging studies for non-invasive imaging of cell migration and cell homing.
