General description

Lucifer yellow CH is a fixable dye with an excitation and emission spectrum of 430 nm and 540 nm, respectively.

application

Lucifer yellow CH dipotassium salt has been used:
  • to visualize cell morphology
  • to assess intercellular communication activity through gap junction by scrape-loading assay
  • as a component of the intracellular solution, which filled the dendrites for the visualization of neuronal morphology
  • in the intracellular solution, to intracellularly label recorded neurons

Features and Benefits

Highly fluorescent dye, useful in marking nerve cells.
