DNA Extraction from Normal and Cancer Tissues in a Section on a Histology Slide

29 Jan 2015

Loss of heterozygosity (LOH) in colon cancer tissue was assessed by PCR using microsatellite markers. DNA was extracted by DEXPAT™ from normal tissue and from neoplastic lesions of formalin-fixed, paraffin-embedded colorectal tumors. To achieve accurate and highly sensitive PCR amplification, DNA extracted with DEXPAT™ is best used in conjunction with TaKaRa Ex Taq™.

DEXPAT Reagent

Takara Bio

DEXPAT Reagent from Takara Bio is designed for one step DNA extraction from paraffin embedded tissue fixed in 10% formalin. DEXPAT Reagent eliminates the laborious deparaffinization, organic solvent extraction and enzymatic digestion steps required in most standard DNA extraction protocols. Furthermore, DEXPAT Reagent enables preparation of PCR-ready DNA in only 25 minutes versus 2-3 days using conventional DNA extraction methods.Because DNA extracted from FFPE samples may be slightly degraded during formalin fixation or paraffin embedding, amplification of products greater than 400 bp is not recommended. The quality of the extracted DNA will strongly depend on the condition of the original embedded tissue.Applications: One Step DNA Extraction from Paraffin Embedded Tissue Extraction of DNA from tissue sections following lengthy storage (up to 10 years) Differential DNA extraction from tissue sections or histology slides

DNA / RNA Extraction and PurificationPurified DNA and RNA are required for numerous downstream molecular biology applications. Consequently, the importance of high-quality DNA/RNA extraction and purification equipment cannot be underestimated. Many purification kits are available and are typically optimized for nucleic acid type and source, including plasmid DNA, genomic DNA, mRNA, RNA and viral nucleic acid purification kits. Automated extraction and purification of nucleic acids can be implemented with magnetic bead separator instruments or high-throughput purification workstations. Find the best DNA/RNA extraction and purification equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Colorectal Cancer
