    Extraction of DNA and RNA from Formalin-fixed Paraffin-embedded Tissue Specimens
    福尔马林固定石蜡包埋组织标本中DNA和RNA的提取

    One of the most common methods for isolating biomolecules from clinical samples is using TRIzol. While many tissues are freshly frozen, a large number of tissues are formalin-fixed paraffin-embedded (FFPE) blocks for pathology and diagnostics.
