Abstract

The disclosure provides methods of capturing target nucleic acids (e.g., gene or gene fragments) onto a solid support for further analysis. The disclosed methods utilize a capture probe that selectively circularizes only the target nucleic acid. Following the circularization of the target, the linear, non-target, nucleic acids are removed from the sample. Next, the circularized target is linearized and bound to a solid support. To allow for linearization, the capture probe may include a cleavage site that can be a noncanonical nucleotide(s) (e.g., uracil in DNA) and/or a rare-cutter site (e.g., the Not I restriction site). In some embodiments, the target nucleic acid is captured onto a support without an intermediate amplification step.
