An Efficient and Easy- to- Use Method for Extraction of DNA from Archival Formalin-Fixed and Paraffin-Embedded Gastric Tissues.

Background & Objective: Formalin-fixed paraffin-embedded archived tissues are useful for the genetic analyses and assessment of some patients' disease history, including infectious diseases. However, there is no established protocol for extracting bacterial DNA from the archived specimens. In this study DNA was extracted from the archived -positive gastric biopsies by some modifications applied to the previously published protocols.
