Water-soluble waxes embedding media have which characteristic regarding dehydration and clearing?

• A. Do not require dehydration and clearing.
• B. Require dehydration and clearing before embedding.
• C. Require dehydration but do not require clearing.
• D. Do not require embedding.

Answer: (A)

Water-soluble wax embedding media are formulated to be compatible with water, so tissues can be infiltrated without removing water and without using clearing solvents. This means dehydration and clearing steps, standard for paraffin embedding, are not required before embedding. The tissue remains in an aqueous or water-compatible environment, which helps preserve antigenicity and simplifies processing for certain stains. Embedding still occurs; you just skip dehydration and clearing.
