An efficient protocol for genomic DNA extraction from formalin-fixed paraffin-embedded tissues.
Formalin-fixed paraffin-embedded tissues (FFPET) represent the largest source of archival biological material available for genomic studies. In this work we present an advanced protocol for extraction of high quality DNA from FFPET that can be applied in several molecular studies. Although cat mammary tumours (CMT) are the third most frequent tumour in cats the recovery of significant number of...
متن کاملAn Efficient Method For DNA Extraction From Paraffin Wax Embedded Tissues For PCR Amplification Of Human And Viral DNA
Background and Objective: Formalin-fixed paraffin-embedded tissues are a valuable source of DNA for molecular studies. We designed and optimized an efficient procedure for DNA extraction from formalin-fixed paraffin embedded tissues. Materials and Methods: Seventy three blocks of cervical paraffin-embedded tissues were investigated. DNA was extracted using 45 minutes boiling in alkaline sol...
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 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...
متن کاملDNA 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...
