Abstract
Methods and apparatus are provided for the recovery of nucleic acids from a nucleic acid-containing material by which nucleic acids can be rapidly and easily recovered at a high purity without deteriorating the yield. The methods are composed of step 1 for promoting the release of nucleic acids from a nucleic acid-containing material, step 2 for mixing the released nucleic acids with an accelerator substance for the binding of nucleic acids to a solid phase, step 3 for bringing the mixture in contact with a solid phase bondable to nucleic acids, step 4 for isolating the solid phase from a liquid, step 5 for washing the solid phase with a solution containing a salt, and a step 6 for eluting the nucleic acids from the solid phase. Accordingly, nucleic acids at a suitable purity for genetic tests or gene analyses can be rapidly and easily recovered without the use of hazardous substances. The apparatus may contain a reactor, at least one pipette, a purified product container, transport mechanisms for the reactor and purified product container, motors to control the pipette and transport mechanisms, a mechanical control unit to control the motors, and a computer that controls the mechanical control unit.
