Streamlined ordering and procurement

Streamlined ordering and procurement

For stock storage and preservation of FFPE tissue, search the iBioSpecimen Marketplace or simply tell our biospecimen experts what you need. No matter how complex the project, we will help improve the entire procurement process, from feasibility to implementation.
Access to healthy donors

Access to healthy donors

In addition to various infectious diseases through our network, we can obtain FFPE blocks from healthy patients or collect normal tissue from the surrounding area to help differentiate between healthy samples and diseases.
Shipping and handling considerations

Shipping and handling considerations

Our team of experts is aware that FFPE blocks require a special delivery facility. FFPE samples are shipped at 70°F to prevent the paraffin from freezing or melting. We also ensure that the use of advertising information is appropriate to optimize data retention.

Understanding Patient Acceptance Level

Many organizations use harvested or stored tissue only to conduct research with consenting patients. With the exception of consent, archived FFPE tissue blocks  data may be the subject of investigation after the retention period has expired.

Finding new or stored approved samples for many types of research, including repeatability, validation and IHC testing can waste your time and money. Archive blocks can be a very good option. Contact us and our model experts will help you find the ideal model for your research.

General FAQ's on FFPE Blocks

An FFPE block is a common method for preserving tissue samples for histological and molecular analysis. It involves fixing tissues in formalin and embedding them in paraffin wax to maintain their structural integrity.

FFPE blocks are used to archive and store tissue samples for long periods while preserving cellular and molecular components. They are essential for pathological diagnosis and retrospective studies.

Tissue samples are first fixed in formalin, dehydrated through a series of alcohol washes, and then embedded in molten paraffin wax. The wax-embedded tissue is then sectioned for analysis.

  • FFPE blocks allow long-term storage of tissue samples at room temperature.
  • They preserve tissue architecture and cellular morphology.
  • FFPE samples are suitable for a wide range of histological and molecular analyses.
  • DNA and RNA extracted from FFPE samples are often degraded, making genetic analysis challenging.
  • Some antigens may be masked, affecting immunohistochemical staining.
  • The fixation process can introduce artifacts.

FFPE tissue can be deparaffinized, and DNA or RNA can be extracted using specific protocols, such as enzymatic digestion or heat-induced methods.

Properly stored FFPE blocks can remain viable for many years, even decades, at room temperature.

Yes, FFPE samples can be used for genetic testing and sequencing, although the quality of DNA or RNA may vary depending on the age and condition of the block.

Proper safety measures should be followed when handling formalin. Additionally, researchers should use clean tools and avoid contamination when sectioning FFPE blocks.

Yes, alternatives include frozen tissue sections (cryopreservation) and fresh tissue samples. Each has its advantages and limitations depending on the specific research or diagnostic needs.

Yes, FFPE blocks are valuable for retrospective studies as they enable researchers to analyze samples collected in the past, providing insights into diseases and treatment outcomes.

FFPE blocks should be stored in a cool, dry place at room temperature. They should be protected from moisture and extreme temperatures.
