Patent number: 9304133Abstract: Methods and apparatus are provided to resolve analytes within a fluid path using isoelectric focusing, gel electrophoresis, or other separation means. Materials within the fluid path that are compatible with these separation means are used to attach resolved analytes to the wall of the fluid path. Attachment results from a triggerable event such as photoactivation, thermal activation, or chemical activation. In accordance with a further aspect of the present invention, the material in the capillary may also be disrupted, by either the triggerable event or a subsequent event such as melting or photocleavage. Thus, an open lumen or porous structure may be created within the fluid path, allowing unbound analyte materials to be washed from the fluid path, and detection agents to be washed into the fluid path. The separation-compatible materials may be polymerizable monomers, gels, entangled polymers or other materials.Type: GrantFiled: April 22, 2011Date of Patent: April 5, 2016Assignee: ProteinSimpleInventors: Roger A. O'Neill, Marc Glazer, Tom W. Yang, Daniel J. Suich, Karl O. Voss

Patent number: 8940232Abstract: 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.Type: GrantFiled: February 27, 2013Date of Patent: January 27, 2015Assignee: ProteinSimpleInventors: David J.

Patent number: 7935479Abstract: Methods for detecting one or more analytes, such as a protein, in a fluid path are described herein. In some embodiments a method includes resolving one or more analytes in a fluid path, such as, for example, a capillary. After the one or more analytes are resolved, the one or more analytes are bound to the fluid path upon activation of one or more triggerable agents disposed within the fluid path. The one or more analytes that are bound to the fluid path are detected within the fluid path.Type: GrantFiled: March 19, 2007Date of Patent: May 3, 2011Assignee: Cell Biosciences, Inc.Inventors: Roger A.

Publication number: 20080124250Abstract: 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.Type: ApplicationFiled: August 17, 2007Publication date: May 29, 2008Inventors: Tom W.
