title: Strand separation of DNA fragments and their isolation from nondenaturing polyacrylamide gels.
abstract: A technique for rapidly and quantitatively denaturing double-stranded DNA employing urea and moderate heat is described. The single DNA strands are resolved on high-percentage nondenaturing polyacrylamide gels from which they can be recovered for Maxam-Gilbert sequence analysis.
