Abstract: Disclosed are high concentration reagents for use in preparing DNA samples in low volume reactions. Such reagents include, for example, DNA end repair buffers for use in low volume DNA blunting and phosphorylating reactions, DNA adenylating buffers for use in a low volume DNA adenylating reaction, and DNA ligation buffers for use in low volume DNA adaptor ligation reactions with adaptors. Also disclosed are customized reagent plates and kits containing one or more of these low volume buffers for use in low volume DNA blunting, phosphorylating, adenylating, and ligation reactions. Methods of using the high concentration reagents (low volume buffers) and the customized reagent plates for preparing DNA sequencing libraries in low volume reactions are also disclosed.

Abstract: High-fidelity, high-throughput nucleic acid sequencing enables healthcare practitioners and patients to gain insight into genetic variants and potential health risks. However, previous methods of nucleic acid sequencing often introduce sequencing errors (for example, mutations that arise during the preparation of a nucleic acid library, during amplification, or sequencing). Provided herein are methods and compositions for sequencing nucleic acids. Further provided are methods of identifying an error in a nucleic acid sequence.
