Abstract: Described herein are methods and systems for performing chemical or enzymatic reactions using electrophoresis. Devices, systems, and methods for preparing a library of tagged nucleic acid fragments from a target double-stranded nucleic acid using electrophoresis are also provided. Application of one or more electric fields causes molecules to migrate through the electrophoresis gel matrix.

Abstract: The assembly includes a docking console and a manifold. The docking console includes a cartridge support surface having a first end and a second end. The manifold has one or more wells defined therein. The docking console further includes a manifold retention bracket to releasably hold the manifold against a fluid cartridge supported on the cartridge support surface at an interface position such that the one or more wells are in fluid communication with the fluid cartridge and a biased seal bar to press the fluid cartridge against the manifold held by the manifold retention bracket. A hydrophilic porous frit disposed within at least one of the wells and is to permit liquid to flow through the outlet aperture but prevent gas from passing through the outlet aperture.

Abstract: Presented herein are methods and compositions for concatenating template strands during the bridge amplification process. The methods are useful for surface amplification at improved densities. The methods and compositions provided herein enable creation of clusters which are brighter, but at the same densities as currently achieved using standard cluster amplification.
