HiPurA® Blood Genomic DNA Midiprep Purification Kit provide a fast and easy method for purification of total DNA from fresh, old (more than 24 hours) and frozen blood. The kit utilizes an advanced silica-based membrane technology in the form of a convenient spin column. The use of spin column facilitates the binding, washing, and elution steps thus enabling multiple samples to be processed simultaneously. It comprises three steps viz. adsorption of DNA to the membrane, removal of residual contaminants and elution of pure genomic DNA. The concentration of DNA can be estimated by agarose gel electrophoresis. Typical yield is 15-50 µg of total DNA from 1-2 ml of whole blood.
