  This study investigated the use of pressure cooking with different retrieval solutions at variable pHs to determine the optimum protocol for the extraction of high quality DNA from formalin fixed paraffin embedded (FFPE) tissues. Further, the oxidation effect on the archived FFPE tissues in relation to the age of the tissue blocks was also explored. The main aim of the study was to investigate this technique on 11 gastric cancers. The design of our study was based on the principles of the antigen retrieval technique using a conventional pressure cooker to improve the quality of DNA extracted from FFPE tissues. In addition to the gastric cancers, lymphoma, breast, prostatic, and colorectal carcinomas were used to eliminate tissue bias. Statistical correlation was done using the paired t-test and Benjamini-Hochberg test. Our findings show that high DNA concentrations were obtained using.. View More»
