    摘要： The invention provides a method for reducing background in hybridization reactions of nucleic acids involving at least two homologous probes, wherein at least one of the probes is non-linear, or two homologous target sequences and a non-linear probe. Background is reduced by introducing an intended mismatch with a target sequence in at least one of the probes. The presence of the mismatch reduces the specificity of probes not entirely complementary to a target sequence to such an extent that the background signal is reduced. A set of mixed homologous probes, wherein at least one of the probes is non-linear, comprising such specific mismatch is also provided. The set can be used for the detection of variants of a family of nucleic acids, for instance a number of HIV variants. The invention also provides kits for carrying out the methods according to the invention.

    摘要： The present application relates to mutated RNA polymerases from bacteriophages that have increased stability, for example under high temperature conditions. One example of bacteriophage encoded RNA polymerase is the T7 RNA polymerase. T7 is a bacteriophage capable of infecting E. coli cells. Examples of other E. coli infecting T7-like bacteriophages are T3, øI, øII, W31, H, Y, A1, croC21, C22 and C23. An example of a Salmonella typhimurium infecting bacteriophage is SP6. The present invention is concerned with the RNA polymerases of T7-like bacteriophages that have been mutated. Due to these mutations the RNAP's have an increased stability. Preferred mutated RNA polymerases according to the invention are mutant RNA polymerases from T7 or SP3 bacteriophages. Due to the high homology between these enzymes, mutations in the T7 gene 1 sequence are likely to have the same effect in the corresponding gene sequence of the T3 bacteriophage. An especially preferred embodiment of the present invention is a T7 RNA polymerase with a serine to proline amino acid change in the protein at position 633 of the amino acid sequence. Since there is 80% homology between the T7 RNA polymerase and the T3 RNA polymerase the same effects of the 633 serine→proline mutation in the T7 gene may be expected for a 634 serine→proline amino acid mutation in the T3 RNA polymerase.

    摘要翻译： 本申请涉及来自具有增加的稳定性的噬菌体的突变的RNA聚合酶，例如在高温条件下。 噬菌体编码的RNA聚合酶的一个实例是T7RNA聚合酶。 T7是能够感染大肠杆菌细胞的噬菌体。 感染T7样噬菌体的其他大肠杆菌的实例是T3，øI，øII，W31，H，Y，A1，croC21，C22和C23。 鼠伤寒沙门氏菌感染噬菌体的一个例子是SP6。 本发明涉及已被突变的T7样噬菌体的RNA聚合酶。 由于这些突变，RNAP具有增加的稳定性。 根据本发明的优选的突变型RNA聚合酶是来自T7或SP3噬菌体的突变型RNA聚合酶。 由于这些酶之间的高同源性，T7基因1序列中的突变可能在T3噬菌体的相应基因序列中具有相同的作用。 本发明的特别优选的实施方案是具有丝氨酸以在氨基酸序列的633位的蛋白质中脯氨酸变化的T7RNA聚合酶。 由于T7 RNA聚合酶和T3 RNA聚合酶之间具有80％的同源性，所以T3 RNA聚合酶中634丝氨酸 - >脯氨酸氨基酸突变可能预期T7基因中63​​3丝氨酸 - >脯氨酸突变的相同作用。

    摘要： Disclosed is a method of quantifying a target nucleic acid in a test sample by adding to the test sample a known number of molecules of a corresponding nucleic acid comprising a well-defined mutant sequence. Said mutant sequence being discriminatory from the target nucleic acid. Subsequently a competitive amplification reaction of the nucleic acid is performed after which quantification of the amplified nucleic acid is performed by a differential detection.
