Publication number: 20200308630Abstract: A method for processing a nucleic acid, in which the nucleic acid is exposed to an aqueous medium which includes a polyol in sufficient proportion for at least a portion of the nucleic acid to enter or remain in an extra-solution phase. Thus, a polyol may be used to bind a nucleic acid which is in solution to a solid support or to wash a nucleic acid on a solid support whilst maintaining it on the support. The polyol may for example be a C2-C10 alkanediol.Type: ApplicationFiled: April 15, 2020Publication date: October 1, 2020Inventors: Darren Ellis, Geir Fonnum, Nini Kjus

Publication number: 20200308631Abstract: Disclosed is a stable double-stranded nucleic acid signal probe in which single-stranded nucleic acids constituting a double-stranded nucleic acid are complementarily crosslinked (or covalently bonded) with each other, and thus are not affected by temperature, pH, salinity, ionic strength, etc. Also disclosed is a method capable of detecting a target molecule by forming a complex of the stable double-stranded nucleic acid signal probe and the target molecule using the signal probe in the detection of the target molecule, separating only the signal probe from the complex by heating or the like, and detecting the signal probe.Type: ApplicationFiled: June 30, 2017Publication date: October 1, 2020Applicant: BIOIS CO., LTDInventor: Sung-Chun KIM
