Tissue Atlas

Stained sections of mirrored samples from formalin fixed, paraffin-embedded (FFPE) and PAXgene Tissue fixed, paraffin-embedded (PFPE) tissues.

The better the source, the more to eXplore.

Our mission is to enable and improve the diagnosis, treatment and monitoring of disease by providing clinicians and researchers with preanalytical systems that yield superior quality samples for molecular diagnostic testing. PAXgene products integrate and standardize the collection, transport, storage, stabilization and purification of nucleic acids from human specimens to optimize the analysis of clinically relevant biomarkers.

PAXgene Blood RNA Tubes, in our experience, represent a chemistry that is easy to handle and almost ideal for work with clinicians and clinical studies, where doctors don't have time for research and need something easy to handle and robust. Also, PAXgene Blood RNA Tubes are already used by different scientific consortia to run large-scale molecular epidemiology studies with thousands of PAXgene tubes stored in their biorepository for later analysis.

Prof. Dr. med. M.Sc. Michael Abend — Bundeswehr Institute of Radiobiology, Germany

We stored blood samples for up to 7 days at room temperature in PAXgene Blood ccfDNA Tubes and used these plasma supernatants and plasma from immediately processed EDTA tubes (so far the "gold standard") from the same cancer patients for molecular analysis of cell-free DNA. Our data demonstrate a very good congruence of the results.
