Abstract

A formulation containing guanidine thiocyanate together with acetamide, one or more acetamide derivatives, or a combination of acetamide and one or more acetamide derivatives is used to purify one or more nucleic acids contained in a medium. In particular, a medium containing at least one nucleic acid is combined with a binding matrix and the formulation in order to cause the at least one nucleic acid to separate from its in vivo cellular environment and to bind to the binding matrix. The binding matrix with at least one nucleic acid bound thereto then is separated from substantially the rest of the combined medium and formulation, after which the at least one nucleic acid is eluted from the binding matrix to obtain the at least one nucleic acid in a substantially purified form. If different nucleic acids are to be selectively purified from a single medium, multiple binding matrices, each compatible with a different nucleic acid, can be used.
