DNA extraction from formalin-fixed, paraffin-embedded tissue.
Several DNA extraction methods have been used for formalin-fixed, paraffin-embedded tissues, with variable results being reported regarding the suitability of DNA obtained from such sources to serve as template in polymerase chain reaction (PCR)-based genetic analyses. We present a method routinely used for archival material in our laboratory that reliably yields DNA of sufficient quality for P...
متن کاملNucleic Acids Extraction from Formalin-Fixed and Paraffin-Embedded Tissues
Formalin-fixed paraffin-embedded (FFPE) tissues are an important sample source for ret‐ rospective studies. Despite its ability to preserve proteins and cell morphology, formalin hinders molecular biology tests since it fragments and chemically modifies nucleic acids, especially RNA. Although several studies describe techniques that allow extracting nu‐ cleic acids from FFPE tissues, so far the...
متن کاملAutomated high throughput nucleic acid purification from formalin-fixed paraffin-embedded tissue samples for next generation sequence analysis
Curation and storage of formalin-fixed, paraffin-embedded (FFPE) samples are standard procedures in hospital pathology laboratories around the world. Many thousands of such samples exist and could be used for next generation sequencing analysis. Retrospective analyses of such samples are important for identifying molecular correlates of carcinogenesis, treatment history and disease outcomes. Tw...
متن کاملProteomic Sample Preparation from Formalin Fixed and Paraffin Embedded Tissue
Preserved clinical material is a unique source for proteomic investigation of human disorders. Here we describe an optimized protocol allowing large scale quantitative analysis of formalin fixed and paraffin embedded (FFPE) tissue. The procedure comprises four distinct steps. The first one is the preparation of sections from the FFPE material and microdissection of cells of interest. In the sec...
متن کاملAn alternative protocol for DNA extraction from formalin fixed and paraffin wax embedded tissue.
BACKGROUND DNA extraction from paraffin wax embedded tissue requires special protocols, and most described methods report an amplification success rate of 60-80%. AIMS To propose a simple and inexpensive protocol consisting of xylene/ethanol dewaxing, followed by a kit based extraction. METHOD Xylene/ethanol dewaxing was followed by a long rehydration step and a kit based DNA extraction ste...
