    • PROBLEM TO BE SOLVED: To provide methods and compositions for quantitative detection of nucleic acid sequences over a wide dynamic range.SOLUTION: Disclosed are compositions and methods for making differentiable amplicon species at unequal ratios using a single amplification system in a single vessel. The number of differentiable amplicon and their ratios to one another are chosen to span the required linear dynamic range for the amplification reaction and to accommodate limitations of the measuring system used to determine the amount of amplicon generated. Unequal amounts of distinguishable amplicon species are generated by providing unequal amounts of one or more amplification reaction components (e.g., distinguishable amplification oligomers, natural and unnatural NTP in an NTP mix, or the like). The amount of target nucleic acid present in a test sample is determined using the linear detection range generated from detection of one or more amplicon species having an amount within the dynamic range of detection.
    • 要解决的问题:提供在宽动态范围内定量检测核酸序列的方法和组合物。解决方案:公开了使用单个扩增系统在单个容器中以不等比例制备可微分扩增子种的组合物和方法。 选择可差分扩增子的数目及其彼此的比例以跨越扩增反应的所需线性动态范围,并适应用于确定产生的扩增子的量的测量系统的限制。 通过提供不等量的一个或多个扩增反应组分(例如,可区分的扩增寡核苷酸,NTP混合物中的天然和非天然NTP等)产生不等量的可区分的扩增子种类。 使用从检测动态范围内的一种或多种扩增子种检测产生的线性检测范围来确定测试样品中存在的靶核酸的量。

    • PROBLEM TO BE SOLVED: To enable the rapid processing of clinical or biological samples, and the rapid and accurate detection of pathogens or antibiotic resistance genes in clinical samples. SOLUTION: There are provided a rapid sample-processing method for preparing hybridization reaction mixtures substantially depleted of RNA, and a method of identifying the methicillin-resistance status and vancomycin-resistance status of an organism. Polynucleotide-based methods, compositions, kits, and devices are provided which can be used for detecting nucleic acids that encode resistance to methicillin and/or vancomycin. More specifically, the invention provides for detection of the mecA gene, which is associated with methicillin resistance of microorganisms, as well as for detection of the VanA and VanB genes, which are associated with vancomycin resistance of microorganisms.
