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.

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.
摘要翻译：通过连接到形成供体/受体染料对的两种染料来修饰单链信号引物。这两种染料位于信号引物足够接近的空间上，第一种染料的荧光被第二种染料淬灭。信号引物还可以包含两种染料之间的限制性内切核酸酶识别位点（RERS）。由于信号引物最初是单链的，并且在不存在靶标的情况下保持单链，限制性内切核酸酶识别位点不受限制性内切核酸酶的切割或切割。然而，在靶的存在下，信号引物和限制性内切核酸酶识别位点被限制性内切核酸酶双链和切割或切割。切割或切口分离两种染料，并且由于猝灭降低引起的荧光变化被检测为目标序列或靶序列扩增的存在的指示。
