Luxol fast blue stain
Luxol fast blue stain, abbreviated LFB stain or simply LFB, is a commonly used stain to observe myelin under light microscopy, first developed by Heinrich Klüver and Elizabeth Barrera in 1953. Luxol fast blue refers to one of a group of three chemically and histologically similar dyes. LFB is commonly used to detect demyelination in the central nervous system (CNS), but cannot well discern myelination in the peripheral nervous system.
