What is the PCR performance of DNA purified from PAXgene Tissue fixed, paraffin-embedded (PFPE) and PAXgene Tissue fixed, cryo-embedded (PFCE) tissue compared to DNA from snap frozen or formalin-fixed, paraffin-embedded (FFPE) tissue?
FAQ ID - 3618

In contrast to FFPE, DNA purified from PFPE and PFCE is of high molecular weight, free of chemical modifications. In demanding downstream applications, such as multiplex or long-range PCR, it performs similarly or identically to DNA isolated from frozen tissue. For examples, see, Figure 5 in Viertler et al., J Mol Diagn. 2012 Sep; 14(5).
