Fig. 2. Differences of DNA quality from formalin-fixed paraffin-embedded (FFPE) tonsil tissues. The concentrations (A) and purity (B) of DNA from FFPE tonsil tissues were similar by various formalin fixatives. The total amount of double-stranded DNA (C) was significantly higher in KoF compared to MdF (*P<0.05). The tape station of double-stranded DNA (D) was significantly higher in MiN compared to LmF and MdF, respectively (**P<0.01). LmF, laboratory-made formalin; MiN, Mirax Co. 10% neutral buffered formalin; MdF, Md force formaldehyde; KoF, Korea CFC chemical Co. formalin.
