Publication number: 20240132979Abstract: A set of primers and probes for simultaneous detection of Cymbidium mosaic virus (CymMV), Odontoglossum ringspot virus (ORSV), and Cymbidium ringspot virus (CymRSV) and a method for detecting CymMV, ORSV, and CymRSV, along with a method for their detection, are disclosed. The method involves designing multiplex real-time quantitative PCR detection primers and probes for CymMV, ORSV, and CymRSV and applying these primers and probes to the real-time quantitative PCR simultaneous detection of CymMV, ORSV, and CymRSV. It allows for faster detection of CymMV, ORSV, and CymRSV, taking only one-third of the time compared to uniplex real-time quantitative PCR technology, thereby reducing testing costs by approximately ? to ½ for each sample. The primers and probes are highly specific and sensitive, with a sensitivity as low as 1 to 10 copies. It provides an efficient and feasible detection method for early detection and prevention of CymMV, ORSV, and CymRSV.Type: ApplicationFiled: January 1, 2024Publication date: April 25, 2024Applicants: FLOWER RESEARCH INSTITUTE OF YUNNAN ACADEMY OF AGRICULTURAL SCIENCES, YUNNAN UNIVERSITYInventors: Lihua Wang, Aiqing Sun, Xuewei Wu, Suping Qu, Yiping Zhang, Xiumei Yang, Yan Su, Feng Xu, Lifang Zhang

Patent number: 6734318Abstract: A method of reacting a first compound to produce a second compound includes the step of contacting a first non-fluorous phase including the first compound with a first fluorous phase at a first phase interface. The first compound distributes between the first fluorous phase and the first non-fluorous phase. The method further includes the steps of contacting the first fluorous phase with a second non-fluorous phase at a second phase interface and including at least a third compound in the second non-fluorous phase that reacts with the first compound to produce the second compound. The second compound has a distribution coefficient less than the first compound. This method can, for example be used to separate the second compound from unreacted first compound wherein, for example, the first compound is of a fluorous nature and distributes more readily into (or transports more quickly through) the fluorous phase than does the second compound.Type: GrantFiled: June 8, 2001Date of Patent: May 11, 2004Assignee: University of PittsburghInventors: Dennis P. Curran, Stephen G. Weber, Hiroyuki Nakamura, Bruno Linclau, Lifang Sun
