摘要:
Devices and techniques for hybridization of nucleic acids and for determining the sequence of nucleic acids. Arrays of nucleic acids are formed by techniques, preferably high resolution, light-directed techniques. Positions of hybridization of a target nucleic acid are determined by, e.g., epifluorescence microscopy. Devices and techniques are proposed to determine the sequence of a target nucleic acid more efficiently and more quickly through such synthesis and detection techniques.
摘要:
A computer system for analyzing nucleic acid sequences is provided. The computer system is used to calculate probabilities for determining unknown bases by analyzing the fluorescence intensities of hybridized nucleic acid probes on biological chips. Additionally, information from multiple experiments is utilized to improve the accuracy of calling unknown bases.
摘要:
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.

摘要:
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.
摘要:
The present invention provides a miniaturized integrated nucleic acid diagnostic device and system. The device of the invention is generally capable of performing one or more sample acquisition and preparation operations, in combination with one or more sample analysis operations. For example, the device can integrate several or all of the operations involved in sample acquisition and storage, sample preparation and sample analysis, within a single integrated unit. The device is useful in a variety of applications, and most notably, nucleic acid based diagnostic applications and de novo sequencing applications.
摘要:
DNA chips containing arrays of oligonucleotide probes can be used to determine whether a target nucleic acid has a nucleotide sequence identical to or different from a specific reference sequence. The array of probes comprises probes exactly complementary to the reference sequence, as well as probes that differ by one or more bases from the exactly complementary probes.
