Different types of histological samples require different storage conditions:
Fresh Tissues: These are typically stored in a refrigerator at 4°C for short-term storage or snap-frozen in liquid nitrogen for long-term storage. FFPE Tissues: Stored at room temperature in dry conditions to prevent moisture damage. Cryostat Sections: Stored in airtight containers at -20°C to -80°C to prevent ice crystal formation and sample degradation. Reagents and Stains: Specific storage requirements vary; for example, some stains need to be refrigerated, while others are stable at room temperature.
