The present invention relates to a method for detecting at least one target nucleic acid sequence from a nucleic acid mixture by a double quenched assay. The double quenched assay of the method exploits a novel approach for melting temperature mediated identification of multiple target nucleic acid sequences. The invention further relates to a kit of parts.

Methods and compositions for the detection and quantification of nucleic acids are provided. In certain embodiments, methods involve the use of cleavable probes that comprise a ribonucleotide position that is susceptible to endoribonuclease (e.g., RNase H) cleavage in the presence of target nucleic acid molecules. Probes of the embodiments may also comprise non-natural nucleotide linked to a reporter and/or quenching moiety.

The present disclosure provides methods and compositions for identifying and discriminating between one or more target nucleic acids within a sample. The disclosed methods may be useful for detecting single nucleotide polymorphisms (SNPs). The disclosed methods may be useful in identifying or detecting the presence or absence of a nucleotide mutation. The use of mutation-specific oligonucleotide probes with universal tails enables specific detection of a SNP target present in a sample.

A method, comprising amplifying a nucleic acid sequence of interest in a sample comprising genomic DNA of a subject; amplifying a reference nucleic acid sequence in the sample; quantifying the amplified sequence of interest relative to the amplified reference sequence; and determining a copy number of the sequence of interest from the relative quantified amplified sequence of interest. The reference sequence may have at least 80% sequence identity to at least one of SEQ ID NO:1-38, such as SEQ ID NO:1-13. Also disclosed are kits and compositions, each comprising a first probe which specifically hybridizes to at least a portion of at least one reference sequence. Also disclosed is a system configured to perform the above method.

Methods are provided for determining a genomic methylation profile in a DNA sample. In certain aspects, the methods can be used to determine if a subject has, or is at risk for developing, a bladder cancer or other cancers of the urinary tract. Methods for treatment of such subjects are likewise provided.
