Abstract: Embodiments include systems, apparatuses, and methods to efficiently separate analytes in a sample and elute fractions of the separated analytes. In some embodiments, a method includes introducing a sample in a capillary with a first end ionically coupled to a first running buffer and a second end ionically coupled to a second running buffer to form a pH gradient. The method includes applying a voltage between the first running buffer and the second running buffer, to separate a plurality of analytes in the sample. The method includes disposing the second end of the capillary in a collection well including a chemical mobilizer and applying a voltage to elute one or more analytes from the plurality of analytes in the sample, that have been separated, into the collection well. Embodiments include detection methods to monitor separation of analytes, mobilization of analytes, and/or elution of fractions containing analytes.

Abstract: Some embodiments described herein relate to capillary-containing cartridges suitable for use with capillary electrophoresis instruments. Embodiments described herein generally relate to cartridges that include a transfer capillary coupled to a separation capillary. The transfer capillary can be configured to be disposed in sample reservoirs and/or buffer reservoirs. Suction applied through a sheath interface of the transfer capillary and the separation capillary can draw sample/buffer from such reservoirs and bring the sample/buffer into contact with the separation capillary. The separation capillary can be configured for separation of analytes contained within the sample, for example when an electric potential (i.e., voltage) is applied across the separation capillary.

The cartridge retainer configured to receive a capillary cartridge having a capillary. The detection assembly includes at least one emitter, a first detector, and a second detector. The detection assembly is configured to transition between a first configuration, in which the first detector detects a first output of the at least one emitter, and a second configuration, in which the second detector detects a second output of the at least one emitter. The reagent tray holder is configured to move relative to the cartridge retainer to place the capillary of the capillary cartridge in fluid communication with a reagent volume.

Abstract: An automated assay system is described with stations for placement of materials to be used in an assay of materials inside capillaries and an automated gripper for manipulating capillaries. The system includes a separation and immobilization station where reactions inside the capillaries take place and a detector station where photoemissions from the capillary reactions are detected. The photoemissions from the capillaries may be displayed as line graphs or in columns of a pseudo-gel image resembling the familiar Western gel blot. An automated control system has a user interface by which an operator can select a run protocol and define the locations of samples and reagents to be used in the protocol run: Following the setup the control system will cause the automated system to execute the protocol, then display the results in a selected display format.

Abstract: A polymeric injection-molded container is described which holds capillaries for a biological material assay system in a vertical position. The container includes a two-piece base which is press-fit together. Ninety-six funnel-shaped holes in the top of the base receive the capillaries and support them circumferentially. Ninety-six apertures in the bottom of the base are tapered to guide the bottom ends of the capillaries to positions aligned with the holes in the top of the base. The inserted capillaries extend above the top surface of the base and are covered by a removable cover. The capillaries can be processed and placed in the container by the capillary manufacturer, shipped to a user in the container, and the container can be placed on the capillary holder station of an automated assay system and used by the automated system directly from the container.

Abstract: A substrate with a plurality of microchannels is movably deployed with other movable objects that will load sample into the microchannels, stimulate molecular migration, read the results of the migration, remove and replace the substrate, and prepare for a new run. The other objects include a gripper for engaging and moving the substrate, an electrode array of fine wires suitable for fitting into the microchannels for electromigration, and a scanning detector for reading migration results. A sequence of automatic operations is established so that one substrate after another may be moved into position, loaded with sample, stimulated for molecular migration, read with a beam, and then removed and replaced with a fresh substrate.
