Several factors influence the storage limits of histological samples:
Temperature: Lower temperatures generally slow down degradation processes. Fixatives: The type and concentration of fixative used can affect the long-term preservation of tissues. Storage Medium: Whether the sample is stored in a paraffin block, cryopreserved, or kept in a fixative solution. Humidity: High humidity can promote mold growth and other forms of degradation. Light Exposure: Prolonged exposure to light can cause photobleaching or other forms of damage.
