Is it possible to archive PAXgene Tissue fixed, paraffin-embedded (PFPE) tissue?

For short-term storage or transport, blocks of PFPE tissue can be stored at 2–25°C. However, biomolecules within the paraffin blocks will undergo slow chemical degradation. For best preservation of morphology and biomolecule integrity within the paraffin-embedded tissue, store PFPE blocks at –20°C (–15°C to –30°C). For the latest results on long-term storage of PFPE and formalin-fixed, paraffin-embedded (FFPE) tissue, see technical notes at PAXgene Tissue Resources.
