The storage temperature depends on the type of sample and the intended duration of storage:
Fresh Tissues: Should be stored at 4°C for short-term preservation (up to 24 hours) to prevent autolysis and bacterial growth. Fixed Tissues: Typically stored in formalin at room temperature for routine histological processing. Long-term storage may require lower temperatures to prevent evaporation of the fixative. Frozen Tissues: Should be stored at -80°C or lower for prolonged storage to prevent ice crystal formation and preserve ultrastructural details.
