Title: Use of extremely thermophilic DNA-polymerases

Abstract: Cycle sequencing of DNA with marker-labeled dideoxynucleotides is performed using extremely thermophilic DNA polymerases in a one-lane technique in which dideoxynucleotides labeled with a dye as a marker are used to obtain sequence ladders of more 500 bases. Chain elongation is performed at a temperature of 65 to 75.degree. C. Surprisingly, it was found that chain elongation temperatures of substantially more than 60.degree. C. could be used in cycle sequencing of DNA with marker labeled dye dideoxynucleotides when using extremely thermophilic DNA polymerases.
