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.

In many butterflies, the ancestral trichromatic insect colour vision, based on UV-, blue- and green-sensitive photoreceptors, is extended with red-sensitive cells. Physiological evidence for red receptors has been missing in nymphalid butterflies, although some species can discriminate red hues well.
