Fig 3. Agarose gel electrophoresis of rat liver DNA.

Fig 3

(A) Agarose gel electrophoresis (0.8%) of 400 ng of purified DNA. DNA on the gel were stained with GelRed which is sensitive to double-stranded DNA. The qPCR ratio to matched frozen tissue DNA is shown at the bottom of each lane. Fro, frozen tissue DNA; Fix., fixation for 1 day (1 d): lanes 2 and 3 were different tissue samples with 1 day fixation, 4 days (4 d) and 5 days (5 d); Heat, heat treatment of lysate (+) or not (-) at 95°C for 30 minutes; M, molecular weight marker; qPCR, qPCR ratio to frozen tissue DNA. (B) Agarose gel electrophoresis (2%) of PCR products with target sizes of 301 bp (a) and 952 bp (b). The rat Tp53 gene was amplified from the indicated DNA, lanes 1 to 8 in (A).
