DNA polymerase blends and mutant DNA polymerases

摘要

A thermostable DNA polymerase composition comprising at least two DNA polymerases, one of which is substantially reduced in 5'-exonuclease activity and one of which has 5'-exonuclease activity. This polymerase may be used in methods including, but not limited to, nucleic acid synthesis, DNA sequencing, nucleic acid amplification and cDNA synthesis.
