20090306359 | NON-ALCOHOLIC BUFFER FORMULATIONS FOR ISOLATING, PURIFYING AND RECOVERING LONG-CHAIN AND SHORT-CHAIN NUCLEIC ACIDS - Embodiments relate to methods and formulations of buffers used for isolating, purifying, and recovering long-chain and short-chain nucleic acids. The areas of application of the inventive method include all laboratories engaged in isolating nucleic acids. In one embodiment a solution containing a nucleic acid is prepared with additives containing monovalent and multivalent cations and, optionally, an alcohol and/or additional additives. The solution is contacted with a solid phase, the solid phase is optionally washed, and the nucleic acid is removed. The solution may contain multivalent and/or monovalent cations and may contain an alcohol. The solution in certain embodiments has a pH between 7 and 10. Ammonium chloride, sodium chloride and/or potassium chloride may be used as monovalent salt components. Magnesium chloride, calcium chloride, zinc chloride and/or manganese chloride may be used as multivalent salt components. In a preferred embodiment, identical molar amounts of sodium chloride and manganese chloride are used. | 12-10-2009 |
