A rapid and inexpensive method for the electroelution of DNA fragments from agarose gels is described. DNA fragments were separated by agarose gel electrophoresis and visualized by staining with ethidium bromide. Selected DNA fragments were placed into electroeluter tubes capped with dialysis membrane and electroeluted into a small volume of buffer using a conventional horizontal gel electrophoresis apparatus. The method successfully eluted and concentrated DNA fragments with molecular weights ranging from 2.7 to 13.9 MDa in 3 h.

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
