METHOD TO ISOLATE DNA

摘要

Presented herewith is a method for isolating DNA from a biological sample. The methods comprise the following sequential steps: separating the biological material comprising DNA from the remainder of the biological sample; contacting the separated biological sample comprising DNA of step (a) with a hypertonic, high salt reagent so as to form a suspension of said biological material comprising DNA; contacting the suspension of step (b) with a lysis reagent to form a lysate comprising DNA and non-DNA biological components released from the biological material; and separating the DNA from the non-DNA biological components in the lysate of step (c) to yield isolated DNA.
