title: Direct sequencing of long polymerase chain reaction fragments.
abstract: Direct sequencing of polymerase chain reaction (PCR)-generated templates is a commonly used technique in molecular biology laboratories. We describe an improved method for direct sequencing of PCR fragments longer than 20 kb obtained with a commercial mixture of Taq and Pwo DNA polymerases. The sequencing protocol was optimized for an automated infrared DNA sequencer, consistently yielding long reads (500-600 bases).
