  • Publication number: 20220154246
    Abstract: This disclosure provides methods and compositions that are useful for enriching a particular population of nucleic acids (a “population of interest”) within a complex mixture of nucleic acids. The population of interest may make up a minor portion of a complex mixture of nucleic acids. The methods and compositions provided herein are useful for detecting, predicting, diagnosing, or monitoring a disease or disorder, particularly a disease or disorder caused by a foreign microbe or pathogen.

  • Patent number: 11299720
    Abstract: Compositions that include polymerases with features for improving entry of nucleotide analogues into active site regions and for coordinating with the nucleotide analogues in the active site region are provided. Methods of making the polymerases and of using the polymerases in sequencing and DNA replication and amplification as well as kinetic models of polymerase activity and computer-implemented methods of using the models are also provided.

  • Patent number: 10815465
    Abstract: Provided are compositions comprising recombinant DNA polymerases that include amino acid substitutions, insertions, deletions, and/or exogenous features that confer modified properties upon the polymerase for enhanced single molecule sequencing. Such properties include increased resistance to photodamage, and can also include enhanced metal ion coordination, reduced exonuclease activity, reduced reaction rates at one or more steps of the polymerase kinetic cycle, decreased branching fraction, altered cofactor selectivity, increased yield, increased thermostability, increased accuracy, increased speed, increased readlength, and the like. Also provided are nucleic acids which encode the polymerases with the aforementioned phenotypes, as well as methods of using such polymerases to make a DNA or to sequence a DNA template.
