Lucifer Yellow CH dipotassium salt (CAS 71206-95-6)

Lucifer Yellow CH dipotassium salt, with the CAS number 71206-95-6, is a highly fluorescent dye that is widely used in biological research for tracing and visualizing cells. This chemical is celebrated for its bright yellow fluorescence and exceptional ability to be retained within cells, making it an invaluable tool for studying cellular morphology and connectivity, especially in neuroscience. The dye′s unique mechanism of action involves its ability to travel through gap junctions, the specialized intercellular connections that allow direct chemical and electrical communication between cells. This property makes Lucifer Yellow particularly useful for studying the connectivity and network properties of neurons and other cell types that communicate via gap junctions. In research, Lucifer Yellow is often injected into cells using microelectrodes, and because it is impermeable to cell membranes once inside, it remains trapped within the cytoplasm, allowing researchers to outline the entire structure of the cell. Furthermore, its ability to diffuse across gap junctions into adjacent cells enables scientists to map networks of connected cells, providing insights into cellular organization and function in various tissues. The dye′s applications extend to confocal microscopy and other advanced imaging techniques, where its bright, stable fluorescence helps in generating detailed, three-dimensional images of cell structures and networks. This has notably enhanced the understanding of complex biological systems without the interference of invasive or toxic effects often associated with other fluorescent compounds.
