ABSTRACT A method for obtaining sequence information directly from plasmid DNA is
presented. The procedure involves the rapid preparation of clean supercoiled plasmid DNA
from small bacterial cultures, its complete denaturation by alkali, and sequence
determination using oligodeoxyribonucleotide-primed enzymatic DNA synthesis in the
presence of dideoxynucleoside triphosphates. The advantages of the method include
speed, simplicity, avoidance of additional cloning steps into single-stranded phage M13 …
Abstract
A method for obtaining sequence information directly from plasmid DNA is presented. The procedure involves the rapid preparation of clean supercoiled plasmid DNA from small bacterial cultures, its complete denaturation by alkali, and sequence determination using oligodeoxyribonucleotide-primed enzymatic DNA synthesis in the presence of dideoxynucleoside triphosphates. The advantages of the method include speed, simplicity, avoidance of additional cloning steps into single-stranded phage M13 vectors, and hence applicability to sequencing large numbers of samples.
