Christian Viertler from the Medical University of Graz in Austria and his colleagues present in the Journal of Molecular Diagnostics their development of a new method to stabilize tissues for analysis. They compared their new approach, called the PAXgene Tissue system, to other stabilization methods like FFPE, PFPE, and snap-frozen on the quantity and quality of their preservation of nucleic acids and other biomolecules. "Importantly, PAXgene-fixed, paraffin-embedded tissues provided RNA quantity and quality not only significantly better than that obtained with neutral buffered formalin, but also similar to that from snap-frozen tissue, which currently represents the gold standard for molecular analyses," Viertler et al. report. Some of the researchers involved in this work are employed by Qiagen or PreAnalytiX, which jointly created the PAXgene Tissue System.
