What is the best way to store FFPE tissue blocks?
FFPE tissue blocks, also known as formalin-fixed paraffin-embedded tissue blocks, are commonly used in diagnostic procedures, particularly in histopathology. Proper storage of these blocks is crucial to preserve the integrity of the tissue and ensure accurate results for future testing. Here are some guidelines on the best way to store FFPE tissue blocks:
- Choose the right storage conditions: It is important to store FFPE tissue blocks in a cool and dry environment. Ideally, the temperature should be maintained between 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) with a humidity level of around 50%. Avoid exposing the blocks to extreme temperatures or fluctuations, as this can cause damage to the tissue.
- Use appropriate containers: Ensure that the FFPE tissue blocks are stored in containers that are resistant to moisture and can provide a tight seal. Plastic containers with screw-on lids or glass jars with rubber gaskets are commonly used for this purpose. These containers should be labeled with the necessary information, such as patient details and date of collection, for easy identification.
- Avoid exposure to light: Prolonged exposure to light can cause degradation of the tissue and affect the quality of the samples. Therefore, it is recommended to store the FFPE tissue blocks in opaque containers or wrap them in light-protective material, such as aluminum foil or black plastic bags.
- Organize and track the storage: Developing an efficient system to organize and track the storage of FFPEtissue blocks is essential for easy retrieval and to prevent mix-ups. Consider implementing a labeling system that clearly indicates the patient’s name, date of collection, and unique identification number. Additionally, keeping a detailed inventory of stored blocks can help ensure proper management and prevent loss or misplacement.
- Maintain proper documentation: It is crucial to maintain accurate and up-to-date documentation of the FFPE tissue blocks. This includes recording the patient’s information, collection date, and any relevant clinical details. Proper documentation not only helps in case review or follow-up testing but also ensures regulatory compliance and quality assurance.
