Title
(EN) METHOD FOR SEPARATING AND PURIFYING NUCLEIC ACID
(FR) PROCÉDÉ DE SÉPARATION ET D’ÉPURATION D’ACIDE NUCLÉIQUE
Abstract
(EN)
A method for separating and purifying nucleic acid, the method comprising: (1) a step of contacting a sample solution containing nucleic acid with a solid phase to adsorb the nucleic acid on the solid phase; (2) a step of contacting a washing solution with the solid phase to wash the solid phase in a state that the nucleic acid is adsorbed on the solid phase; and (3) a step of contacting a recovering solution with the solid phase to desorb the nucleic acid from the solid phase, wherein the sample solution is prepared by including a step of removing a precipitate component, and adding a surfactant and a water-soluble organic solvent to a supernatant solution of the precipitate.
(FR)
L’invention concerne un procédé de séparation et d’épuration d’acide nucléique, le procédé comprenant : (1) une phase de mise en contact d’une solution échantillon contenant un acide nucléique avec une phase solide pour adsorber l’acide nucléique sur la phase solide ; (2) une phase de mise en contact d’une solution de lavage avec la phase solide pour laver la phase solide sur laquelle l’acide nucléique est adsorbé ; et (3) une phase de mise en contact d’une solution de récupération avec la phase solide pour désorber l’acide nucléique de la phase solide, la solution échantillon étant élaborée en englobant une phase d’enlèvement d’un composant précipité, et en ajoutant un tensioactif et un solvant organique soluble dans l’eau à une solution excédentaire du précipité.
