Abstract:
Purification of DNA fragments from acrylamide or agarose gels is a commonly used technique in the molecular biology laboratory. This article describes a rapid, efficient, and inexpensive method of purifying DNA fractions from an agarose gel. The purified DNA is suitable for use in a wide range of applications including ligation using DNA ligase. The procedure uses standard high-melting-temperature agarose and normal TBE electrophoresis buffer. In addition, the protocol does not involve the use of highly toxic organic solvents such as phenol.

Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...

Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
