Abstract: Systems, methods, and compositions for monitoring and analyzing nucleic acid hybridization state using L-DNA probes are described. The methods include adding L-DNA probes that can be fluorescently detected to a system including D-DNA. The L-DNA probes include primer, target, and antisense nucleotide sequences, and fluorescent dye compounds. The L-DNA probes are particularly useful for monitoring and analyzing various parameters during DNA amplification using the polymerase chain reaction.

Abstract: The invention relates to methods for the determination and detection of nucleic acids sequences in a sample. The nucleic acid may be RNA or DNA or both. The invention also relates to methods for the determination of the presence and species of various microorganisms in a sample. We have also identified a set of oligonucleotide nucleic acid sequences within the rRNAs of Gram-negative organisms that facilitates both the broad identification of Gram-negative organisms as a class when used as a pool, or in combination, for example in a hybridization assay. This set of oligonucleotides may detect sequences that are indicative of the presence of organisms of the broad class of Gram-negative organisms while exhibiting little or no false identification of Gram-positive organisms, and fungi, or other microorganisms. The assay includes concurrent incubation with at least one nucleotide sequence of interest, at least one nucleic acid probe, a fluorosurfactant, and a nuclease.

Abstract: Methods and kits for use in isolating, labeling or detecting a small polynucleotide of interest from a sample. The method entails hybridizing the small polynucleotide to a capture probe, lengthening the small polynucleotide by primer extension and/or ligation, and degrading the capture probe to provide a single stranded extension product. The kits include the capture probe and additional reagents for the extension, ligation and/or degradation reactions.
