  • All of our material is well annotated.
  • Diseased/tumor and adjacent normal tissues from a single donor are immediately available in formalin fixed paraffin embedded (FFPE) format.
  • Snap frozen is available in limited quantities.
  • Fresh FFPE tissue samples are collected prospectively from ongoing clinical protocols.
  • All material is either consented or supplied under “waiver of consent”.
  • All FFPE tissue is supplied by our fully-owned subsidiary, California Tissue Consortium.

General Information About FFPE Tissue

PrecisionMed Inc. provides FFPE Tissue samples to some of the world's leading researchers.Because formalin-fixed, paraffin-embedded (FFPE) tissues may be stored almost indefinitely at room temperature, and nucleic acids (both DNA and RNA) may be recovered from them for a significant time after fixation, along with the fact that our samples include detailed clinical data, they provide a key resource for researchers.

Due to the high-quality of PrecisionMed, Inc.’s  FFPE tissue samples, our customers gain a critical advantage when extracting DNA or RNA.

Other Embedding Methods

Embedding can also be performed using frozen, non-fixed tissue in a water-based medium. Using a water-based glycol, TBS, OCT, Cryogel, or resin, pre-frozen tissues are placed into molds and then frozen to form hardened blocks.
