No phenol–chloroform extraction is required. DNA binds specifically to the QIAamp silica-gel membrane while contaminants pass through. PCR inhibitors, such as divalent cations and proteins, are completely removed in three efficient wash steps, leaving pure DNA to be eluted in either water or a buffer provided with the kit. QIAamp technology yields genomic and mitochondrial DNA from blood and other body fluids ready to use in PCR and blotting procedures.
Fresh and frozen whole blood with common anticoagulants, such as citrate, EDTA, and heparin, may be processed with additional equipment and the use of a special protocol available from QIAGEN Technical Services or your local distributor.
