The present invention provides compositions, kits and methods for the selective hybridization and capture of a specific target nucleic acid. The specific target nucleic acid may be present in a heterogeneous mixture of nucleic acids. Selective hybridization and capture provides a target nucleic acid that is substantially free of non-target and/or contaminating nucleic acids. Target nucleic acids that have been selectively hybridized and captured using the current invention are then used in subsequent analysis, wherein the presence of non-target and/or contaminating nucleic acids that interfere with said subsequent analysis have been substantially reduced or eliminated, thereby providing improved analysis results. The invention offers the further advantage of requiring less stringent purification and/or sterility efforts than conventionally needed in order to ensure that enzymes and other reagents used in subsequent analysis, or present in the environment in which an assay is performed, are free of bacterial or other contaminating nucleic acids.

In some embodiments, methods for ligating nucleic acid ends comprise: conducting a nucleic acid ligation reaction in the presence of at least one agent that generates a ligatable terminal 5′ phosphate group by removing an adenylate group from a terminal 5′ phosphate of a nucleic acid. In some embodiments, an aprataxin enzyme can catalyze removal of an adenylate group from a terminal 5′ phosphate of a nucleic acid. In some embodiments, methods for ligating nucleic acid ends comprise: conducting a nucleic acid ligation reaction in the presence of an aprataxin enzyme under conditions suitable for ligating nucleic acid ends.

The present invention provides methods for immobilizing target nucleic acids on a solid support utilizing combinatorial capture probe pairs. These pairs contain first and second capture oligonucleotides that each comprise a target binding region, a capture region and a stem region positioned between the target binding and capture regions. The target binding regions comprise nucleic acid sequences that allow them to hybridize to adjacent regions on the target nucleic acid. The stem regions have nucleic acid sequences that are complementary to each other and the capture regions each comprise a sequence that when positioned adjacent to one another produce a combined nucleic acid sequence that is complementary to a portion of an oligonucleotide bound to a solid support. When the first and second capture oligonucleotides are annealed to the target nucleic acid, the stem regions are brought together allowing them to hybridize, which in turn brings the capture regions together to produce a combined nucleic acid sequence. This combined nucleic acid sequence is then able to hybridize to the oligonucleotide bound to the solid support thereby immobilizing the target nucleic acid.
