Lucifer yellow is afluorescent dye used incell biology.[1] The key property of Lucifer yellow is that it can be readily visualized in both living and fixed cells using afluorescence microscope. Lucifer yellow was invented by Walter W. Stewart at theNational Institutes of Health and patented in 1978.[2]
For common usage it is compounded withcarbohydrazide (CH) and prepared as alithiumsalt. The CH group allows it to becovalently linked to surrounding biomolecules duringaldehydefixation.[3]
Othercations such asammonium orpotassium can be used when lithium is undesirable, but the resulting salts are less soluble in water.
Lucifer yellow can also be compounded as avinylsulfone, withethylenediamine, or withcadaverine.[clarification needed]
