Abstract:
Methods and compositions for the detection and quantification of nucleic acids are provided. In certain embodiments, methods involve the use of cleavable probes that comprise a ribonucleotide position that is susceptible to endoribonuclease (e.g., RNase H) cleavage in the presence of target nucleic acid molecules. Probes of the embodiments may also comprise non-natural nucleotide linked to a reporter and/or quenching moiety.

The invention further relates to kits and uses associated with the method.
Abstract:
This invention relates to the preparation of nucleic acid samples for analysis. The invention may be particularly useful for single stranded samples. Embodiments of the invention involve the attachment of double stranded or hairpin oligonucleotides using template independent polymerase enzymes in the preparation of nucleic acid sequencing libraries.
Abstract:
Disclosed are methods and materials for detecting RNA in a sample. In some forms, the method involves (a) bringing into contact the sample and a probe array, (b) bringing into contact the probe array and a ribonuclease specific for RNA/DNA hybrids (such as RNase H), (c) bringing into contact the probe array, labeled nucleotides, and a nucleic acid polymerase capable of extending a RNA strand using a DNA template and capable of incorporating the labeled nucleotides in the extension from the RNA strand (such as Klenow fragment DNA polymerase), and (d) detecting the labeled nucleotides in the extended nucleic acid strand. The probe array comprises one or more chimeric probes. The chimeric probes comprise a DNA region and a RNA region, where the DNA region and the RNA region are contiguous and where the DNA region is 5' of the RNA region. The chimeric probe can also include a second DNA region. The second DNA region can also be contiguous with the RNA region and can be 3' of the RNA region.

일 구체예는 일 양상은 만성골수성백혈병 유전자에 특이적으로 결합하는 프라이머 쌍 및 상기 프라이머쌍에 의해 증폭되는 만성골수성백혈병 증폭 산물의 내부에 특이적으로 결합하는 절단 가능한 프로브를 포함하는 만성골수성백혈병 유전자의 발현량을 검출하는 검출용 키트를 제공하는 것이고, 다른 구체예는 일 구체예 따른 검출용 키트를 이용하여 시료에 있는 만성골수성백혈병 유전자의 발현량을 측정하는 것이다. 구체예의 방법을 이용할 경우, 낮은 농도의 만성골수성백혈병 유전자의 발현량도 효율적으로 실시간으로 검출하여 만성골수성백혈병 진단 및 예후 진단에 유용하게 이용할 수 있다.
Abstract:
The present invention relates to the detection of a target nucleic acid sequence by a PCEC (PTO Cleavage and Extension-Dependent Cleavage) assay. The present invention is characterized by generating a cleavage site for a nucleolytic enzyme on the extended duplex of which the formation is dependent on the presence of a target nucleic acid sequence. The present invention detects the occurrence of the cleavage of the extended duplex, thereby determining the presence of the target nucleic acid sequence.
