Cresyl echt violet staining yields violet for which component?

Explanation:
Cresyl echt violet is a classic Nissl stain. It binds strongly to the acidic ribosomal RNA in the rough endoplasmic reticulum of neurons, staining the Nissl bodies in the cell body a deep violet. This makes the neuron’s soma and its characteristic Nissl material stand out, which is why this stain is used to assess neuronal morphology and cytoarchitecture. It does not specifically stain myelin, which is better labeled withLuxol Fast Blue, and while nuclei may take up some stain, the defining violet structures in this method are the Nissl bodies.
