The CellVue Burgundy cell labeling kit uses proprietary membrane labeling technology to stably incorporate CellVue Burgundy, a fluorescent dye with long aliphatic tails, into lipid regions of the cell membrane1. The labeling buffer provided with the kit (Diluent C) is an iso-osmotic aqueous solution which contains no physiologic salts or buffers, detergents, or organic solvents and is designed to maintain cell viability while maximizing dye solubility and staining efficiency. The labeling efficiency of staining is dependent upon the cell type being labeled and the membranes of the cells2, 3.
Use NIR Fluorescent Labeling for Cell Tracking and Cell Proliferation Studies
CellVue products have been reported to be useful for short-term in vitro cell proliferation studies4, cell tracking in isolated organ preparation applications5, and cell tracking using the Pearl® Small Animal Imaging System or Odyssey® CLx or Odyssey Classic Infrared Imaging System6.
- CellVue Burgundy dye stock (1 vial containing 0.1 mL, 1 x 10-3 M in ethanol)
- Diluent C (1 vial containing 10 mL, sufficient for 5 labeling reactions)
Excitation and Emission Properties of CellVue Burgundy Dye
The excitation and emission properties of CellVue Burgundy dye are compatible with a range of commercially available near-infrared fluorescent plate readers, flow cytometers, in vitro and in vivo fluorescent imaging systems, and confocal microscopes.
