dye coupling


dye coupling
Measure of intercellular communication, usually through gap junctions. If a fluorescent dye (eg. lucifer yellow) injected into one cell is seen to pass into a neighbouring cell, the presence of junctions at least able to pass solutes of that size can be inferred between the two. See also electrical coupling.
