How is Fresh Tissue Preserved for Histological Analysis?
To preserve fresh tissue for histological analysis, several methods can be employed:
1. Cryopreservation: Rapid freezing of tissue using liquid nitrogen or specialized cryopreserving agents helps maintain the native state. 2. Refrigeration: Keeping tissue at 4°C can slow down degradation temporarily. 3. Specialized Media: Solutions like RNA later can stabilize RNA and other molecules in fresh tissue.
