Study Notes
Tissue Storage and Preservatives
- Preservative solutions are used to prevent tissue degradation and maintain tissue structure for future analysis, ensuring the integrity of stored specimens.
FFPE in Immunohistochemistry
- Formalin-fixed paraffin-embedded (FFPE) tissue is beneficial for immunohistochemistry due to its ability to preserve antigenicity, allowing for effective antibody-antigen reactions.
Fixative Choice in Histopathology
- The choice of fixative is crucial in histopathology and tissue storage as it affects tissue morphology, antigenicity, and overall sample quality, influencing the accuracy of diagnoses and research findings.
Stored Specimens in Research
- Stored specimens play a vital role in retrospective investigations and research, enabling the re-examination of tissues using new techniques or assays, and facilitating the discovery of new biomarkers and therapeutic targets.
FFPE Blocks for Long-term Storage
- FFPE blocks are suitable for long-term storage due to their ability to maintain tissue morphology and antigenicity, making them an ideal choice for biobanking and future research applications.
