Separation of nucleic acids from a liquid sample using a liquid flow device

摘要

A method for purifying nucleic acid from a liquid sample. The methods comprises: applying a liquid sample containing a nucleic acid and other components to a sample receiving section of a lateral flow device which contains a bibulous membrane, in particular cellulose or nitrocellulose, which does not carry any specific binding agents for nucleic acids; causing or allowing the liquid sample to flow along the membrane to distribute the nucleic acid along the entire length of the membrane to sufficiently separate the nucleic acid from the other components and allow detection of the nucleic acid; and in a subsequent step detect or recover the nucleic acid from a region of the membrane.
