Abstract: A sample containing particles having high-molecular-weight (HMW) DNA is entrapped in a gel matrix, and the gel matrix is exposed to a lysis reagent configured to release the HMW DNA from the particles. The HMW DNA may be purified by subjecting the gel matrix to an electrophoretic field that removes the HMW DNA from the particles, lysis reagents, and/or other sample constituents, from the gel matrix such that the HMW DNA remains. The gel matrix may be subjected with DNA cleavase re-agents configured to cleave at specific DNA sequences within the HMW DNA to liberate defined segments of the DNA as fragments of reduced size. The gel matrix may also be subjected to an electrophoretic field, which moves and separates the DNA fragments from uncleaved DNA of the HMW DNA, which remains substantially immobile. The electrophoretically separated DNA fragments may be isolated from the gel matrix.

Abstract: Various implementations disclosed herein relate to automated processing of nucleic acids and electrophoretic sample preparation. An exemplary disposable cassette for automated molecular processing may include a base housing, a central channel arranged in the housing, and an elution module configured to be received in central channel and to divide the central channel into a first chamber and a second chamber. The elution module comprises a housing having a proximal side, a distal side and an elution module channel passing from the proximal side to the distal side. The elution module also comprises a first membrane attached to a proximal side of the elution module, a second membrane attached to a distal side of the elution module, and a porthole in fluid communication with the elution module channel and configured for receiving a sample.

Abstract: Systems and methods for processing fluid samples are disclosed. Fluid sample processing is accomplished using a series of microfluidic bump arrays include an automated and integrated system for sorting particles from a biological sample, lysing those particles to expose total RNA or DNA, purifying the RNA or DNA, processing the RNA or DNA by chemical or enzymatic modification, to select RNA or DNA molecules by size, or to generate, optionally, a sequencing library. The sequencing library is suitable for use in next generation sequencing (“NGS”).
