Dna Polymerases Having Strand Displacement Activity

摘要

The invention provides novel strand displacement DNA polymerases which can be used in a rapid and efficient strand displacement amplification reactions. The polymerases are significantly more thermostable than prior art polymerase and retain high activity at elevated temperatures. Also disclosed are genes encoding the polymerases and vectors comprising the genes. Representative polymerases of the invention are obtainable from bacterial strains of the species Thermus antranikianii and Thermus brockianus and also from environmental samples with isolation of the source species.
