Abstract: The invention provides arrays of immobilized probes, and methods employing the arrays, for detecting mutations in the biotransformation genes, such as cytochromes P450. For example, one such array comprises four probe sets. A first probe set comprises a plurality of probes, each probe comprising a segment of at least three nucleotides exactly complementary to a subsequence of a reference sequence from a biotransformation gene, the segment including at least one interrogation position complementary to a corresponding nucleotide in the reference sequence. Second, third and fourth probe sets each comprise a corresponding probe for each probe in the first probe set.

Abstract: A method, device and system for hybridizing a target oligonucleotide to at least one array comprising a plurality of mixing beads are provided. A target solution is mixed by agitating the mixing beads while the target oligonucleotides are hybridizing to the complementary probes on the array. In another embodiment, a permeable barrier contains the mixing beads, thereby preventing them from contacting the array surface.

Abstract: The invention provides arrays of immobilized probes, and methods employing the arrays, for detecting mutations in the CFTR gene.

Abstract: The present invention relates to novel methods for sequencing and mapping genetic markers in polynucleotide sequences using Type-IIs restriction endonucleases. The methods herein described result in the “capturing” and determination of specific oligonucleotide sequences located adjacent to Type-IIs restriction sites. The resulting sequences are useful as effective markers for use in genetic mapping, screening and manipulation.

Abstract: The present invention generally provides a rapid efficient method for analyzing polymorphic or biallelic markers, and arrays for carrying out these analyses. In general, the methods of the present invention employ arrays of oligonucleotide probes that are complementary to target nucleic acids which correspond to the marker sequences of an individual. The probes are typically arranged in detection blocks, each block being capable of discriminating the three genotypes for a given marker, i.e., the heterozygote or either of the two homozygotes.

Abstract: Methods of detecting nucleic acids, proteins and cells including methods of detecting two or more nucleic acids, proteins and cells in multiplex bDNA assays, are provided. Assays may be conducted at least in vitro, in vivo, in cellulo, and in situ. Nucleic acids are detected, through cooperative hybridization that results in specific association of a label probe system with target nucleic acids. Embodiments are directed to concurrent detection of one or more nucleic acids and/or one or more proteins. The detected proteins may be intracellular or external markers on the surface of the cell. Detection of protein components is accomplished by use of specific antibodies and a label probe system and/or coated microparticles which bind to the outside surface of specific cells and contain specific probes that can be detected using the same label probe system. Compositions, kits, and systems related to the methods are also described.

Abstract: Methods of detecting various types of nucleic acids, including methods of detecting two or more nucleic acids in multiplex branched-chain DNA assays, are provided. Detection assays may be conducted at least in vitro, in cellulo, and in situ. Nucleic acids which are optionally captured on a solid support are detected, for example, through cooperative hybridization events that result in specific association of a label probe system with the nucleic acids. Various label probe system embodiments are provided. Compositions, kits, and systems related to the methods are also described.

Abstract: The present invention provides for novel methods of sample preparation and analysis involving reproducibly reducing the complexity of a nucleic sample. The invention further provides for analysis of the above sample by hybridization to an array which may be specifically designed to interrogate the desired fragments for particular characteristics, such as, for example, the presence or absence of a polymorphism. The invention further provides for novel methods of using a computer system to model enzymatic reactions in order to determine experimental conditions before conducting actual experiments.
