Lucifer Yellow: A fluorescent dye that was introduced in 1978. It is based on the chemical luciferin discovered in 1888 that is present in luminescent organisms such as fireflies. It has proven to be a fiendishly useful product with many applications. In this experiment, it is used in a dissolved form and injected into a neuron, but it has also been used with good effect for immunohistochemistry. Lucifer Yellow fluoresces with bright yellow-green color when stimulated with ultraviolet (wavelength 280 nm) or blue (wavelength 430 nm) light. Because of this, to view the fluorescence, you need an expensive halogen or mercury high-pressure lamp and appropriate filters to block out UV, which can damage your eye. This set-up will cost $3,000 or more, in addition to the cost of the microscope.
