Rapid and reliable dideoxy sequencing of double-stranded DNA

Gene. 1985;40(2-3):317-23. doi: 10.1016/0378-1119(85)90055-1.


We report a simple and reliable protocol for nucleotide sequencing using the Sanger dideoxy technique on linearized double-stranded DNA molecules with specific oligonucleotide primers. The method is demonstrated for restriction fragments cloned into the plasmid vectors pSP64 and pSP65 using two vector-specific primers, the M13 reverse primer and a new SP6 primer, flanking the multiple cloning site. Template DNA may be prepared by a rapid alkaline lysis procedure. Mild linearization conditions with the appropriate restriction endonuclease avoid the appearance of artifact bands.
