Which step in tissue processing acts as the 'bridge' between dehydration and infiltration, using a reagent miscible with both alcohol and paraffin?
Show answer and explanation
Correct answer: Clearing
Clearing involves replacing the dehydrating fluid with a solvent, such as Xylene, that is miscible with both alcohol and the embedding medium (paraffin). It also gives the tissue a translucent appearance due to the change in its refractive index.
