RNASE H2 MUTANTS THAT REDUCE PRIMER DIMERS AND OFF-TARGET AMPLIFICATION IN RHPCR-BASED AMPLICON SEQUENCING WITH HIGH-FIDELITY DNA POLYMERASES

摘要

The present invention pertains to hybrid RNase H2 proteins that include fragments of amino acid sequences from Pyrococcus abyssi ( P.a.), Thermococcus kodakarensis (T.kod), and Pyrococcus furiosus organisms, as well as methods of using the same to improve mismatch discrimination and activity in a high-fidelity DNA polymerase buffer.
