    • Described herein is a new approach in which a nucleic acid species of interest (e.g. a chromosome) containing multiple unique target sequences is detected using multiple specific probes that are amplified by rolling circle amplification and detected. Multiple probes are used to provide a detectable signal, where the magnitude of the signal is proportional to the number of probes recognising their target sequences. Individual signals from the plurality of probes are converted into a single cumulative detectable signal, amplifying the individual signals through the multiplex probing. Ten or more probes produce a signal amplification of ten-fold or more. The generated signals depend on correctly reacted probes upon target recognition, using sequence specific hybridisation and enzymatic catalysis to generate specific products from which the signal is obtained.
    • 本文描述了一种新方法,其中使用通过滚环扩增和检测扩增的多个特异性探针检测含有多个独特靶序列的目标核酸种类(例如染色体)。 使用多个探针来提供可检测信号,其中信号的大小与识别其靶序列的探针的数量成比例。 来自多个探测器的各个信号被转换成单个累积可检测信号,通过多路探测放大各个信号。 十个或更多个探针产生十倍或更多倍的信号放大。 产生的信号取决于靶标识别时正确反应的探针,使用序列特异性杂交和酶促催化以生成从中获得信号的特定产物。
