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.

Monitoring and analysis of nucleic acid hybridization state and amplification using L-DNA

A capture probe suitable for use with a method for isolating miRNAs. A method for isolating an miRNA of interest from a sample comprising the miRNA of interest comprising providing the capture probe. A method for identifying an miRNA of interest.

Method and substances for isolating miRNAs

A spin column device, which contains a rigid porous filter that retains its shape during centrifugation, chromatography methods using the device to isolate a desired substance, e.g., a biological molecule, from other substances in a mixture, and kits containing the device with one or more reagents for use in the method.

Devices and methods for the purification, isolation, desalting or buffer/solvent exchange of substances

A method for labeling biological molecules and synthetic molecules that contain a geminal diol, such as RNA, carbohydrates or glycoproteins, using a periodate sequestering agent is provided. Compositions and kits for use in the labeling method are also provided.

Method, substances and kits for labeling population of RNA and other substances containing vicinal diols

A primer set used to screen a polynucleotide sample to detect and identify variants in the Cytochrome P450 isoenzyme 2D6 (CYP2D6) gene. A method of screening a polynucleotide sample to detect and identify the presence of one or more than one variant in the CYP2D6 gene in the sample. A method of predicting the potential for altered metabolism of a substance, including one or more than one pharmaceutical drug, by a first individual compared to a second control individual, where the substance is metabolized by the CYP2D6 isoenzyme, and where the second control individual is homozygous for the wild type allele of the CYP2D6*1, SEQ ID NO:1. A method of screening a population to detect and identify the presence of one or more than one variant in the CYP2D6 gene. A purified or isolated variant of SEQ ID NO:1. A purified or isolated variant of SEQ ID NO:3.

Cytochrome P450 genetic variations

A method of determining the presence and identity of a variation in a nucleotide sequence between a first polynucleotide and a second polynucleotide comprising, first, providing a sample of the first polynucleotide and selecting a region of the first polynucleotide potentially containing the variation. Then, the selected region is subjected to a template producing amplification reaction to produce a plurality of double stranded polynucleotide templates which include the selected region. Next, a family of labeled, linear polynucleotide fragments is produced from both strands of the template simultaneously by a fragment producing reaction using a set of primers. Then, the location and identity of at least some of the bases in the selected region of the first polynucleotide is determined using the labels present in the fragments. Next, the location and identity of the bases determined is compared with the location and identity of bases from a second polynucleotide, thereby identifying the presence and identity of a variation in a nucleotide sequence between the selected region of the first polynucleotide and a corresponding region of the second polynucleotide.

Method for determining polynucleotide sequence variations

A method of making a pool of individual DNA molecular weight markers of defined base pair lengths that are resolved from one another and have substantially equal band intensities and that span the desired range of base pair lengths; the resultant pool of DNA molecular weight markers; the method of determining the presence of a nucleic acid or the length thereof in a specimen suspected of containing a nucleic acid utilizing such resultant pool of markers, and kits utilizing the method of making the pool and/or utilizing the markers.

Method for the multiplexed preparation of nucleic acid molecular weight

An immunochemical assay to determine the presence or concentration of antigen or antibodies in a fluid, comprising: (a) forming a ternary complex of a first labelled antibody or antigen, a second labelled antibody or antigen, and the antigen or antibody to be determined; and (b) detecting a signal produced in the presence of at least one substrate, by an interaction between said first label and said second label, enhanced by their proximity to each other bound to the antigenic substance.
