Patent number: 10934539Abstract: Methods of isolating nucleic acids comprising DNA from biological material are disclosed. The methods comprise a lysis step using an aqueous composition which comprises lithium at a concentration of 0.05 to 1.0M, a chelating agent, and a surfactant to produce a lysed composition. The lysed composition is treated with a solid support that is capable of immobilising DNA in the presence of a dissolved chaotropic agent at a concentration of 0.05 to 2M and 25% to 60% by volume of a C1-3 alkanol. The support is then washed with a first wash solution containing lithium dissolved in a C1-3 alkanol. Subsequently, the support is washed with a liquid comprising at least 80% by volume of a C1-3 alkanol. The nucleic acid comprising DNA is then eluted from the support.Type: GrantFiled: March 17, 2016Date of Patent: March 2, 2021Assignee: RevoluGen LimitedInventors: Stephen John Minter, Georgios Patsos
