Fresh Frozen Tissue Samples
All fresh frozen tissue samples are collected under IRB approval by certified medical pathologists.
- Standard sample weight is 0.5 – 1.0 gram.
- Tissues are stored in vapor-phase liquid nitrogen (-190°C).
- Frozen tissues are never allowed to thaw after initial freezing.
- Any diseased tissue specimen may be individually ordered, or paired with its FFPE tissue or fluid sample (ie. blood or biofluid), or NAT (normal adjacent tissue)
