Abstract
The invention features methods and apparatus for concentrating a nucleic acid. Methods of the invention include providing an initial suspension of a nucleic acid and an initial liquid, contacting the initial suspension with a housing having a filter that does not pass the nucleic acid, pressurizing the housing to produce a filtrate and a nucleic acid retentate from the initial solution, and detecting the volume of the nucleic acid retentate. Apparatus of the invention include a chamber configured to hold a filter housing containing a nucleic acid suspension, a pressure source to filter the suspension, and a detector to depressurize the housing upon detecting the volume reaching a predetermined threshold. The methods and apparatus described herein are useful in filtering, concentrating, and reconstituting nucleic acids, such as mRNA, in processes such as complete buffer replacement.
