title: DNA sequencing by the chemical method.
abstract: This procedure is written for a novice with no chemical sequencing experience. It is assumed, however, that the investigator has experience with DNA fragment isolation and DNA labeling with [32P]dNTPs. A DNA fragment labeled at only one end with 32P or 35S is divided into four aliquots and subjected to base-specific modification reactions. Piperidine is then added to catalyze strand scission at the modified bases. Finally, the four reactions are subjected to electrophoresis on adjacent lanes of a high-resolution denaturing polyacrylamide gel. The gel is then autoradiographed and the sequence is read from the film.
