  • ISOLATION OF NUCLEIC ACID
    Publication number: 20170037394
    Abstract: A method for isolating a nucleic acid comprises: binding the nucleic acid to a solid phase at a first pH in the presence of a binding buffer, washing the bound nucleic acid with a wash solution, and eluting the nucleic acid from the solid phase at a second pH which is higher than the first pH. The wash solution comprises a buffer with a buffering range that encompasses a pH that is higher than the first pH, and the wash solution is at a pH that is within a buffering range of the binding buffer but lower than the buffering range of the buffer of the wash solution. Solutions, compositions, and kits for use in the methods are described.
