Both processing methods—formalin-fixed paraffin-embedded (FFPE) and flash-frozen—effectively preserve biospecimens. However, the choice between them depends upon the specific application.
FFPE
Advantages
- Can be stored at room temperature for an extended period
- Advantageous for immunohistochemical (IHC) staining
- Cost-effective
- Widespread availability
Disadvantages
- Formalin is toxic and typically not suitable for molecular analysis
- Processing protocols lack standardization, resulting in samples being processed differently. It is crucial to have a biorepository with strict Quality Assurance and Quality Control processes in place
Flash frozen
Advantages
- Suitable for molecular analysis, including DNA/RNA quality and extraction, and gene expression and sequencing
- Maintains sample integrity and molecular viability
- Suitable for mutation analysis
Disadvantages
- Increased shipping expenses
- Deteriorates at room temperature
- Not suitable for IHC staining
