Lucifer Yellow CH is a highly sensitive yellow fluorescent dye widely used in neurobiology, cytology, and molecular biology for cell tracing, studying cell-cell interactions, and visualizing neurons. The dye is suitable for labeling both live and fixed preparations: it has low cytotoxicity, is retained in cells after fixation (e.g., with paraformaldehyde), and is compatible with most immunochemistry protocols. Lucifer Yellow CH has a high quantum yield, is resistant to photobleaching, and is, therefore, ideal for confocal and fluorescence microscopy.

The main dye application:

  • Neuronal tracking: Dye injection allows for tracking the morphology of axons and dendrites in vivo and in vitro.
  • Iontophoresis: Used to label individual cells in electrophysiological studies.
  • Transfection: Compatible with microinjection and electroporation methods.

Working dye concentration: 1–5% (depending on protocol).
