General description

Lucifer yellow CH is a fixable dye with an excitation and emission spectrum of 430 nm and 540 nm, respectively.LuciferYellow CH (LYCH) is a small, hydrophilic molecule, and highly fluorescent dye that is used for intracellular staining for the studies conducted on various types of cells. It acts as a marker for the detection of well-established tight junctions in smooth muscles, glia, and interstitial cells of Cajal (ICC).

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.
