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

PFPE tissue blocks can be stored at 2–25°C for short-term storage or transport. However, biomolecules within paraffin blocks will undergo slow chemical degradation. To better preserve morphology and biomolecule integrity within the paraffin-embedded tissue, store PFPE blocks at–30°C to –15°C. For the latest results on long-term storage of PFPE and formalin-fixed, paraffin-embedded (FFPE) tissue, see poster RT-PCR Performance of RNA Obtained from Archived FFPE and PFPE Blocks of Tissue under the Product Resources tab.
