    Abstract: 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.

    Abstract: The present invention provides nucleic acid amplification systems and methods that desirably reduce or eliminate false positive amplification signals resulting from contaminating biological material, e.g., nucleic acid, that may be present in one or more reagents used in an amplification reaction and/or that may be present in the environment in which an amplification reaction is performed. 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 amplification reactions, and the environment in which an amplification reaction is performed, are free of bacterial or other nucleic acid contamination that may yield false positive results.

    Abstract: Compositions, reaction mixtures, kits and methods used in amplifying and detecting nucleic acids from various species of the class Mollicutes. Particular regions of the 23S rRNA or its gene have been identified as preferred targets for nucleic acid amplification reactions of a sample suspected containing at least one species of Mollicutes. Some oligomers comprise tag regions, target closing regions, promoter sequences, and/or binding moieties. Samples can be from any source suspected of containing a species of the class Mollicutes. Preferred sample sources include bioreactors, cell lines, cell culture wares and pharmaceutical manufacturing wares.

    Abstract: Compositions, reaction mixtures, and methods for performing an amplification reaction, including multiplex amplification reaction, wherein the method comprises using one or more amplification oligomer complexes comprising linked first and second amplification oligomer members. In one aspect, the amplification oligomer complex is hybridized to a target nucleic acid, the target nucleic acid with hybridized amplification oligomer complex is then captured, and other components are washed away. Target sequences of the target nucleic acids are pre-amplified to generate a first amplification product. The first amplification product is amplified in one or more secondary amplification reactions to generate second amplification products.
