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.

The present invention relates to the evaluation of the performance of a component using a pair of dimer-forming primers. The method using the pair of dimer-forming primers according to the present invention can be used not only for evaluating the performance of components including a nucleic acid polymerase but also as an internal control in the detection of a target nucleic acid sequence.

The disclosure relates to engineered systems and methods for detecting target nucleic acid in a sample, which may be a complex mixture. The systems and methods may improve sensitivity of target nucleic acid detection by enhancing signal generation. For example, signal generation may be enhanced through programmable capture and concentration of the target nucleic acid using an engineered type III CRISPR complex. Various ancillary nucleases such as Can1, Can2, and NucC are identified and may be used for detection. For example, binding of the engineered type III CRISPR complex may produce products that activate the identified ancillary nucleases. Different activators trigger changes in the substrate specificity of these nucleases. The activated nucleases may be used to detect programmatic detection of the target nucleic in the sample. The systems and methods are shown to detect viral RNA directly from nasopharyngeal swab samples.
