    Abstract: The present application provides methods and compositions for use in detecting the presence of a target nucleic acid in a sample. In some embodiments, the methods employ sequestering agents which specifically interact with complementary nucleic acids which will be ligated together if the target nucleic acid is present in the sample. Detection of a ligation product comprising the complementary nucleic acids indicates that the target nucleic acid is present in the sample.

    Abstract: A universal tag assay is disclosed wherein at least one invasive cleavage reaction (ICR) is used to generate tagged molecules having identifier tags corresponding to target nucleotide sequences, and further wherein hybridization of any tagged molecule with a complementary detection probe on a universal detector indicates the presence of the corresponding target in the sample being assayed. Preferred embodiments include the use of ICR to generate molecules suitable for use in the universal tag assay to detect variant nucleotide sequences including single nucleotide polymorphisms (SNPs), allelic variants, and splice variants. Hybridization of tagged molecules to detection probes is preferably detected by electrochemical readout, in particular the use of ruthenium amperometry to detect hybridization of identifier tags to detection probes immobilized on a universal detector, preferably a universal chip having gold or carbon electrodes.

    Abstract: The present invention disclosure provides methods and compositions for a universal tag assay wherein a universal detector having detection probes is incubated with tagged molecules having identifier tags corresponding to targets, and hybridization of an identifier tag to a complementary detection probe indicates the presence of the corresponding target in the material being assayed. In particular, the invention disclosure provides methods and compositions for detecting target nucleotide sequences in a sample by target-dependent manipulations that generate tagged molecules having identifier tags corresponding to target nucleotide sequence, where incubation of tagged molecules with a universal detector having detection probes permits hybridization of identifier tags to complementary detection probes, thereby indicating the presence of the target nucleotide sequence corresponding to each identifier tag. Preferred embodiments include use of the universal tag assay for detecting variant sequences including single nucleotide polymorphisms (SNPs), allelic variants, and splice variants. Preferred embodiments further include the use of ruthenium amperometry to detect hybridization of tagged DNA or RNA molecules to detection probes immobilized on a universal detector, preferably a universal chip having gold or carbon electrodes.

    Abstract: The present disclosure relates to methods for generating single-stranded DNA molecules of defined sequence and length using ligase chain reaction (LCR). Specifically, a region of template containing target sequence is amplified by LCR, exogenous sequence is introduced by LCR primers or probes used in amplification, and LCR products may be used in further amplification steps involving rolling circle amplification (RCA) or polymerase chain reaction (PCR). LCR products may include sequence complementary to the backbone of a padlock probe, where the LCR product hybridizes to a padlock probe and after ligation of the padlock, serves as polymerazation primer. After amplification, single-stranded amplification products are trimmed to produce short single-stranded DNA molecules of defined sequence and length.
