PCR analysis of DNA purified from FFPE tissue samples.

Genomic DNA was purified from different FFPE tissue samples using the QIAamp DNA FFPE Tissue Kit. Products of the prnp gene (78 bp, 464 bp, and 727 bp) were amplified by real-time quantitative PCR.

QIAamp DNA FFPE Tissue Kit procedure.

Paraffin is dissolved in xylene and removed. The sample is lysed under denaturing conditions with a short proteinase K digestion. Incubation at 90°C reverses formalin crosslinking. DNA binds to the membrane and contaminants flow through. Residual contaminants are washed away. DNA is eluted in Buffer ATE or water, and is immediately ready for use in amplification reactions or for storage at –20°C. Purified DNA is free of proteins, nucleases, and other impurities.
