    摘要: A method of interrupting the expression of a macromolecular synthesis operon in bacteria comprising the step of binding an antisense oligonucleotide to a single stranded DNA or to a mRNA transcribed from the macromolecular synthesis operon. The antisense oligonucleotide can be either sequence specific to a unique intergenic sequence or a sequence specific to a bacterial homologous sequence. By interrupting the expression of the macromolecular synthesis operon bacterial infections can be treated. Specific antisense oligonucleotides are disclosed. The ability of the antisense oligonucleotide to bind the mRNA or single stranded DNA also allows the identification of the bacteria by using a unique intergenic antisense oligonucleotide to bind to the single stranded DNA or to the mRNA transcribed from the macromolecular synthesis operon. A method for competitively inhibiting the protein products of the MMS operon with oligonucleotides is also disclosed. Methods of identifying unique intergenic sequence is also disclosed.

The device comprises a well for placement of a rotaxane comprising the combination of a cyclic molecule and a linear polymer threaded through said cyclic molecule; a probe having the ability to move the linear polymer relative to the cyclic molecule while producing a signal resulting from the interaction of the cyclic molecule and a unit attached to the polymer; and means for reading said signal. The process comprises formation of the rotaxane, attachment of the probe, movement of the cyclic molecule relative to the linear polymer and the reading of signals. The device and method are especially useful for the sequencing of DNA.

    摘要: Method for detecting macromolecular biopolymers using a unit for immobilizing macromolecular biopolymers, in which the unit is provided with first molecules serving as capture molecules. The method includes the steps of bringing a sample into contact with the unit, it being possible for the sample to contain the macromolecular biopolymers, and the macromolecular biopolymers or the first molecules having a marking which is used to generate a detectable signal, binding macromolecular biopolymers contained in the sample to the capture molecules, thereby forming complexes comprising capture molecules and macromolecular biopolymers, exciting the emission of a signal by means of the marking, detecting the signal emitted by means of the marking, separating the complexes comprising capture molecules and macromolecular biopolymers, thereby altering the intensity of the emitted signal, and detecting the separation of the complexes comprising capture molecules and macromolecular biopolymers by means of the change in the intensity of the signal.

    摘要: The invention relates to generating a signal indicative of a target nucleic acid sequence, comprising forming a complex by incubating a sample comprising a target nucleic acid sequence with a probe comprising a first and second subunit, and a binding moiety, and dissociating the first and second subunit to release the first subunit and generate a signal. The invention also relates to a method of generating a signal indicative of the presence of a target nucleic acid sequence in a sample, comprising forming a complex by incubating a target nucleic acid sequence, an upstream primer and a probe comprising a first and second subunit, and a binding moiety. The primer is extended with a nucleic acid polymerase to displace a portion of the first subunit from the target nucleic acid strand thereby dissociating the first subunit from the second subunit to release the first subunit and generate a signal.

    摘要: Single-stranded signal primers are modified by linkage to two dyes which form a donor/acceptor dye pair. The two dyes are positioned in sufficiently close spatial proximity on the signal primer that the fluorescence of the first dye is quenched by the second dye. The signal primer may further comprise a restriction endonuclease recognition site (RERS) between the two dyes. As the signal primer is initially single-stranded and remains single-stranded in the absence of target, the restriction endonuclease recognition site is not cleavable or nickable by the restriction endonuclease. In the presence of target, however, signal primer and the restriction endonuclease recognition site are rendered double-stranded and cleavable or nickable by the restriction endonuclease. Cleavage or nicking separates the two dyes and a change in fluorescence due to decreased quenching is detected as an indication of the presence of the target sequence or of target sequence amplification.
