Luxol Fast Blue stains which tissue component?

Explanation:
Luxol Fast Blue specifically highlights the lipid-rich myelin sheath that surrounds many nerve fibers. The dye has an affinity for myelin lipids, so areas with myelination stain blue, making it an excellent tool for evaluating white matter and detecting demyelination. Neurons (cell bodies) and blood vessels are not selectively stained by this dye, which is why Luxol Fast Blue is paired with other stains when those components are needed. In practice, it’s common to use Luxol Fast Blue with Cresyl Violet to simultaneously visualize myelin and neuronal cell bodies, aiding in identifying demyelinating conditions.
