    摘要: The invention provides a sample preparation device for processing a plurality of fluid samples comprising: (a) a plurality of sample processing chambers connected in parallel, each chamber having an internal surface and inlet and outlet ports; (b) media chambers disposed within each sample processing chamber, each media chamber comprising: (i) a bottom frit attached to and extending across the sample processing chamber; and (ii) a top barrier attached to and extending across the sample processing chamber between the bottom frit and the inlet port, wherein the top barrier, bottom frit and internal surface define a media chamber having a first average cross-sectional area; and (c) a bed of separation medium positioned inside the media chamber. In certain embodiments, the top barrier is a frit and/or the separation medium comprises gel resin beads.

    摘要: The invention provides extraction columns for the purification of an analyte (e.g., a biological macromolecule, such as a peptide, protein or nucleic acid) from a sample solution, as well as methods for making and using such columns. The columns typically include a bed of extraction media positioned in the column, often between two frits. In some embodiments, the extraction columns employ modified pipette tips as column bodies. In some embodiments, the invention provides methods characterized by the use of hydrophobic and/or hydrophilic membranes as frits, and/or by the inclusion of a wad of fibrous material to act as a wicking agent.

The columns typically include a bed of extraction media positioned in the column between two frits. In some embodiments, the extraction columns employ modified pipette tips as column bodies. The invention also provides methods for using the extraction columns including methods for varying parameters, such as the volume of sample loaded, the number of capture cycles performed, and the number or wash cycles performed to achieve a particular desired result.
