Tissue blocks that are formalin-fixed, paraffin-embedded (FFPE) are now a crucial component of pathology, clinical diagnostics, and scientific research. They provide a dependable way to preserve biological materials, preserving the integrity of cellular shape and allowing for long-term storage for a range of scientific uses. In addition to its usefulness for efficiently storing samples, FFPE Tissue Samples are important for molecular research, FFPE Tissue Blocks for Biomarker Discovery, genetic analysis, and the study of disease development.

This article will discuss the importance in Human and Animal FFPE Blocks for Research Purposes. We’ll also discuss how Ibio Specimens, a reputable supplier of superior biological samples, helps the scientific community by providing High Quality FFPE Samples for Pathology Labs.

What Are FFPE Blocks?

The following steps are involved in the preparation of FFPE tissue blocks:

1. Fixation: To maintain the structural integrity of cells and stop deterioration, tissue samples are submerged in formalin.

2. Dehydration: A sequence of alcohol baths is used to progressively dehydrate the fixed tissues.

3. Embedding: To stabilise and solidify the sample for long-term storage, the dehydrated tissues are embedded in paraffin wax.

The Importance of FFPE Blocks in Biobanking.

In biobanking, FFPE blocks are essential because they provide:

• Long-Term Preservation: Researchers can access historical samples for retrospective studies since FFPE tissue blocks can be kept for years without degrading significantly.

• Ease of Handling: The tissue is protected from physical harm and contamination by the solid paraffin matrix, which facilitates manipulation and transportation.

• Versatility for Various analysis: FFPE samples can be utilised for molecular analysis, such as the extraction of DNA, RNA, and proteins, immunohistochemistry, in situ hybridisation, and histological investigations.

Applications of FFPE Tissue Blocks in Research.

1. Pathology and Diagnostic Research

FFPE tissue blocks are the gold standard in pathology labs for the diagnosis of genetic abnormalities, infectious illnesses, and cancer. To investigate tissue architecture, cellular morphology, and the existence of particular biomarkers, pathologists depend on High Quality FFPE Samples for Pathology Labs.

2. FFPE Tissue Blocks for Biomarker Discovery

Finding molecular signatures linked to diseases is known as biomarker discovery, and it is one of the most important uses of FFPE blocks. In order to investigate gene expression patterns, mutations, and protein markers—and ultimately develop diagnostic tests and targeted therapies—researchers can extract nucleic acids and proteins from FFPE samples.

3. Human and Animal Research Studies

Human and Animal FFPE Blocks for Research Purposes are used in veterinary research to examine translational studies, comparative pathology, and zoonotic illnesses. 

4. Retrospective Cohort Studies

Researchers can examine preserved tissues from previous clinical trials or epidemiological investigations using FFPE samples because of their long-term stability, which makes them perfect for retrospective cohort studies.

How to Store FFPE Tissue Blocks Properly.

Proper storage of FFPE tissue blocks is essential to maintain their quality and reliability for research. Here are some best practices:

1. Maintain Optimal Temperature and Humidity

• Temperature: Store FFPE blocks at a consistent, cool temperature (ideally 4°C to room temperature) to prevent wax degradation.

• Humidity: Avoid high humidity environments, as moisture can cause paraffin to become soft, leading to sample degradation and contamination.

2. Use Proper Storage Containers

Blocks should be kept out of the elements in airtight, moisture-proof containers. To guarantee correct identification and traceability, prominently label each block.

3. Avoid Repeated Freezing and Thawing

The structural integrity of the tissue may be impacted by frequent temperature changes, even though FFPE blocks are usually stable. To stop deterioration, keep samples in stable settings and handle them as little as possible.

4. Protect from Light Exposure

Fluorescent dyes (if present) may photodegrade when exposed to intense artificial light or direct sunshine, which can lower the quality of molecular analyses. If required, store samples in dark areas or use opaque containers.

Challenges : How to Store FFPE Tissue Blocks Properly and How to Overcome Them.

Despite their strength and adaptability, FFPE blocks have several drawbacks, particularly in molecular research:

• Nucleic Acid Degradation: Cross-linking of nucleic acids brought on by formalin fixation might make it challenging to extract high-quality DNA or RNA.

• Solution: Make use of kits and specific extraction procedures made for FFPE samples, such those provided by Ibio Specimens.

• Problems with Antigen Retrieval: Over time, some proteins may become less antigenic.

• Solution: Use efficient antigen retrieval strategies, such as enzymatic or heat-induced epitope retrieval (HIER).
