title: Electroblotting of double-stranded DNA for hybridization experiments: DNA transfer is complete within 10 minutes after pulsed-field gel electrophoresis.
abstract: A rapid, simple, and efficient method for DNA blotting is presented. This method is characteristic in that DNA is transferred without denaturation from an electrophoretic gel to a membrane in low-salt concentrations and denatured on the membrane after blotting. More than 89% of double-stranded DNAs ranging in size from 75 to 1.9 million bp can simultaneously be transferred from the gel to a positively charged nylon membrane within 10 min. The present "low-salt electroblotting" method is superior to other blotting methods in that it saves time and labor and its high and even transfer efficiency makes it useful for hybridization analysis.
