Abstract
Provided are methods for preparing a library of target nucleic acid sequences, as well as compositions and uses therefor. Methods comprise contacting a nucleic acid sample with a plurality of adaptors capable of amplification of one or more target nucleic acid sequences under conditions wherein the target nucleic acid(s) undergo a first amplification; digesting the resulting first amplification products; repairing the digested target amplicons; and amplifying the repaired products in a second amplification, thereby producing a library of target nucleic acid sequence. Each of the plurality of adaptor compositions comprise a handle and a targeted nucleic acid sequence and optionally one or more tag sequences. Provided methods may be carried out in a single, addition only workflow reaction, allowing for rapid production of highly multiplexed targeted libraries, optionally including unique tag sequences. Resulting library compositions are useful for a variety of applications, including sequencing applications.
