The present invention pertains to a process for the chromatographic separation of nucleic acid mixtures into their double-stranded and single-stranded nucleic acid fractions by simultaneously absorbing said nucleic acids as a whole to a mineral support, followed by separation into double-stranded and single-stranded nucleic acids by fractional elution, or by selectively absorbing double-stranded or single-stranded nucleic acid of a liquid sample to a mineral support, as well as solutions and a kit for performing the process according to the invention.

Process for the separation of double-stranded/single-stranded nucleic acid structures

A method for the purification and separation of nucleic acid mixtures by chromatography including adsorbing the nucleic acids to be separated and purified from a solution with a high concentration of salts (ionic strength) and/or a high concentration of alcohol on a substrate and subsequent desorbing from the substrate by means of a solution with lower concentration of salts (ionic strength).

Chromatographic purification and separation process for mixtures of nucleic acids

A device and a process for isolating nucleic acids by lysing intact cells and removing nucleic acids emerging from the lysed cells by the following steps:
