[Use of a nylon membrane for purifying DNA fragments from agarose gels]
Abstract:
A new and effective technique was proposed for rapid 30-40 minisolation of pure double-stranded DNA fragments from agarose gels and their use for nick-translation, for restriction with cutting enzymes and ligation with vector DNA. The technique developed involved an electrophoretic transferring of a DNA fragment from the gel into a strip of nylon membrane with the pore size of 0.2 mm followed by elution with buffer containing 0.1% SDS. Yield of the DNA fragment with a length up to 8.0 Kbp was at least 50%. Advantages of the technique developed as compared with standard methods are discussed.

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.

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...
