paraffin-embedded tissue

Paraffin-embedded tissue is a common method used in medical laboratories to preserve tissue samples for examination. The process involves fixing the tissue with chemicals to prevent decay, then infiltrating it with melted paraffin wax. Once cooled, the tissue becomes solid and can be sliced into very thin sections for microscopes. This preservation allows researchers and doctors to study the tissue's cellular structure and identify diseases like cancer. Paraffin embedding is essential for detailed analysis, long-term storage, and accurate diagnosis, making it a vital step in pathology labs.
