Luxol Fast Blue (LFB) - Cresyl Violet Staining - Diagnostic Applications

When neuronal injuries occur, Nissl substance is lost. If axon degeneration is present, the myelin covering also breaks down. The loss of Nissl substance (chromatolysis) and the breakdown of the myelin (demyelination) are indicative of neural injuries and other diseases like Alzheimer's. By combining the LFB and cresyl violet staining procedures, BOTH Nissl substance and myelin can be demonstrated, or the lack thereof.
