Title
(EN) ISOLATION OF NUCLEIC ACIDS
(FR) ISOLEMENT D'ACIDES NUCLÉIQUES
Abstract
(EN)
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.

L'invention concerne des procédés d'isolement d'acides nucléiques comprenant l'ADN d'un matériel biologique. Les procédés comprennent une étape de lyse utilisant une composition aqueuse qui comprend du lithium à une concentration de 0,05 à 1,0 M, un agent chélatant et un tensioactif afin de produire une composition lysée. La composition lysée est traitée avec un support solide qui peut immobiliser l'ADN en présence d'un agent chaotropique dissous à une concentration de 0,05 à 2 M et de 25 % à 60 % en volume d'un alcanol en C1-3. Le support est ensuite lavé avec une première solution de lavage contenant du lithium dissous dans un alcanol en C1-3. Ensuite, le support est lavé avec un liquide comprenant au moins 80 % en volume d'un alcanol en C1-3. L'acide nucléique comprenant l'ADN est ensuite élué du support.
