Formalin-Fixed Paraffin Embedded (FFPE) Tissue

Extensive inventory of deeply-characterized, pathologist-reviewed FFPE tissue blocks, curls, and slides
FFPE tissue specimens are collected under IRB-approved protocols from high-caliber CLIA- and CAP-certified laboratories and hospitals in the US and our international partners and stored in our on-site climate-controlled biorepository. Our inventory contains a wide variety of disease and normal tissue, which undergo extensive pathologist review to ensure only the highest-quality samples are delivered to you. Precision’s network of partner hospitals and laboratories allow us to prospectively collect samples for indications not in our repository.

Precision’s tissue archive represents benign, chronic and acute disease, and oncology indications. 

  • Tissues aged 2-10+ years old
  • Large-volume subset of oncology indications successfully sequenced with highly annotated molecular data, many of which with banked RNA/DNA
  • Suitable for biomarker screening studies, prevalence studies, TMA construction, additional genomic profiling, client-proprietary IHC optimization and validation studies

Bringing you the highest quality tissues

With a full-service histopathology lab and on-site pathologists, Precision's FFPE tissue undergoes the highest level of quality control – with the capacity for customizable characterization – before shipping straight to your lab. 
  • Sample Curation
  • Real-Time Tissue Review
  • Additional Characterization
  • Pathologist-verified tissues for your research

    Following each tissue request, samples are hand-selected from our inventory and annotated by our on-site, research-focused pathologists to match samples with your exact needs – ensuring each sample delivered meets only the highest-quality standards for your downstream applications.
  • Digital Pathology solutions for biomarker confirmation and collaborations

    All of our FFPE tissue blocks that have undergone genomic characterization have matched H&E slide images that allow for pre-selection of your tissue blocks based on biomarker data, ensuring the samples selected have what you need. Whole slide images are available for all tissues upon request via Proscia Concentriq. 

    This digital pathology program also allows for real-time collaboration for IHC validations across labs and pathologists. 

  • On-site histopathology and genomics lab to further characterize your samples

    Our integrated, high-throughput histology lab allows for additional annotation and tissue processing, such as custom staining or TMA creation.

    Over 13,000 of our FFPE tissue blocks across 15 oncology indications have been sequenced via NGS and are accompanied by variant data, H&E slide images, and isolated DNA/RNA.
