  • Patent number: 9994840
    Abstract: A method of extracting DNA from a biological sample includes the steps of freezing a biological sample; mechanically breaking down the sample to produce a processed sample; mixing the processed sample with a lysis solution; and cycling the mixture through a series of pressure fluctuations to produce a resulting lysate. The method may further include the steps of exposing the lysate to a material that binds to DNA present in the sample and collecting the DNA from the sample using an elution solution. An apparatus for practicing the method includes a first segment for mechanically breaking down the sample; a second segment for pressurizing a mixture of the processed sample and lysis solution to produce a lysate; and wherein the first segment is fluidly coupled to the second segment. The apparatus may also include a third segment in which the lysate is exposed to the binding material.
