摘要:
The invention relates to the generation and characterization of archaeal DNA polymerase mutants with reduced base analog detection activity. The invention further provides for archaeal DNA polymerase mutants with reduced base analog detection activity containing additional mutations that modulate other DNA polymerase activities including DNA polymerization or 3'-5' exonuclease activity. The invention also discloses methods and applications of DNA polymerases with reduced base analog detection activity.
摘要:
The invention relates to baseline subtraction algorithms developed to reduce tube-to-tube and cycle-to-cycle variabilities during real time PCR amplification. Particularly, the invention relates to algorithms for determining the threshold cycle for the first reliable detection of the amplified nucleic acid product. The invention also relates to computer programs comprising the algorithms and methods and/systems implementing the algorithms.
摘要:
The invention provides methods of covalently joining nucleic acid molecules and methods of molecular cloning. The methods provide either sequential or simultaneous ligation of flanking or vector nucleic acid molecules to nucleic acid insert molecules by topoisomerase and DNA ligase. The methods provide for directional and non-directional covalent joining and cloning of nucleic acid molecules.
摘要:
The invention features a novel isolated Family B DNA polymerase, a Thermococcus polymerase JDF-3, and mutant recombinant forms thereof. Mutant polymerases of the invention are deficient in 3’ to 5’ exonuclease activity and/or exhibit reduced discrimination against non-conventional nucleotides relative to the wild-type form of the polymerase.
