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:

1. 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.
   
   
2. 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.
   
   
3. 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.
   
   
4. 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.
   
   
5. 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.

Can FFPE tissue blocks be used for DNA analysis?

Yes, FFPE tissue blocks can be used for DNA analysis. FFPE (Formalin-Fixed Paraffin-Embedded) tissue blocks are commonly used in pathology laboratories to preserve tissue samples for long-term storage.

DNA analysis can be performed on FFPE tissue blocks to extract and analyze genetic material. The process involves several steps, including deparaffinization, DNA extraction, and purification.

Deparaffinization is the first step, where the paraffin wax is removed from the tissue block. This is typically done by incubating the block in a series of solvents. Once the paraffin is removed, the DNA can be extracted from the tissue sample.

There are various DNA extraction methods available, such as using commercial kits or manual extraction methods. These methods involve breaking down the tissue and disrupting the cells to release the DNA.

After the DNA is extracted, it needs to be purified to remove contaminants and impurities that may interfere with the analysis. This is typically done using purification kits, which utilize filtration or binding techniques to isolate the DNA.

Once the DNA is purified, it can be used for various DNA analysis techniques, such as PCR (Polymerase Chain Reaction), DNA sequencing, or genotyping. These techniques can provide valuable information about genetic mutations, gene expression, or other genetic characteristics.
