Principle
Tissue DNA Purification Kit provides optimal DNA-binding conditions and the lysate is loaded onto the DNeasy Mini Spin Column. DNA is selectively bound to the DNeasy membrane as contaminants pass through. Remaining contaminants and enzyme inhibitors are removed in two efficient wash steps and DNA is then eluted in water or buffer, ready for use. Purified DNA has A260/A280 ratios of 1.7–1.9, and absorbance scans show a symmetric peak at 260 nm confirming high purity.
The DNeasy membrane combines the binding properties of a silica-based membrane with simple spin column technology. DNA adsorbs to the DNeasy membrane in the presence of high concentrations of guanidine salt, which remove water from hydrated molecules in solution. Buffer conditions in the QIAwave DNA Blood & Tissue procedure are designed to enable specific adsorption of DNA to the silica membrane and optimal removal of contaminants and enzyme inhibitors.
