The most common methods for long term storage in histology include:
1. Paraffin Embedding: Tissues are fixed, dehydrated, cleared, and embedded in paraffin wax. This method is widely used due to its ability to preserve tissue morphology and cellular details. 2. Cryopreservation: Tissues are rapidly frozen and stored at very low temperatures using liquid nitrogen or ultra-low temperature freezers. This method is suitable for preserving biomolecules and enzyme activities. 3. Formalin Fixation: Tissues are fixed in formalin and stored in a formalin solution. This method is often used for routine histological examinations and immunohistochemistry.
