  • Methods and reagents for the polymerase chain reaction amplification of long DNA sequences
    Patent number: 5512462
    Abstract: Methods and reagents are provided for the amplification of DNA sequences longer than 10 kilobases by the polymerase chain reaction (PCR). The methods use compositions consisting of a primary thermostable DNA polymerase from Thermus thermophilus combined with a lesser amount of a secondary thermostable DNA polymerase possessing a 3'-to-5' exonuclease activity from Thermococcus litoralis, Pyrococcus species GB-D or Thermotoga maritima. The DNA polymerase compositions, when used with the disclosed reaction buffer, enable amplifications of DNA sequences up to at least 42.2 kilobases in length.
