description EL INVENTO SE REFIERE A METODOS EFECTIVOS Y SEGUROS PARA LA EXTRACCION DE ACIDOS NUCLEICOS. EN PARTICULAR, SE DESCRIBEN METODOS PARA AISLAR ACIDO NUCLEICO DE UNA MUESTRA QUE CONTIENE UNA MEZCLA BIOLOGICA DE ACIDO NUCLEICO Y OTROS COMPUESTOS BIOLOGICOS DONDE LA MUESTRA SE COMBINA CON UNA SOLUCION DE EXTRACCION QUE CONTIENE AL MENOS UN COMPUESTO ORGANICO COMO BENCILALCOHOL O UN DERIVADO DE BENCILALCOHOL PARA FORMAR UNA FASE ACUOSA O NO ACUOSA. EL ACIDO NUCLEICO SE AISLA DE LA FASE ACUOSA. PREFERENTEMENTE LA SOLUCION COMBINADA RESULTANTE CONTIENE TAMBIEN BENTONITA, COMO SE DEFINE POSTERIORMENTE. TIPICAMENTE, LA MUESTRA SE COMBINARA EN PRIMER LUGAR CON UN AGENTE DE LITICO ANTES DE LA EXTRACCION. LOS AGENTES LITICOS PREFERIDOS SON SALES CAOTROPICAS COMO HIDROCLORURO DE GUANIDINIUM O ISOTIOCIANATO DE GUANIDINIUM. This invention relates to safe and effective methods for the extraction of nucleic acids. In particular, methods are described for isolating nucleic acid from a sample containing a biological mixture of nucleic acids and other biological compounds wherein the sample is combined with an extraction solution containing at least one organic compound such as benzyl alcohol or a benzyl alcohol derivative to form an aqueous and non-aqueous phase. The nucleic acid is isolated from the aqueous phase. Preferably, the resulting combined solution also contains bentonite, as defined below. Typically, the sample will first be combined with a lysing agent before extraction. The lysing agents preferred are chaotropic salts such as guanidinium hydrochloride and guanidinium isothiocyanate.
