Patent number: 7056430Abstract: The cell-delivery unit of a high-throughput electrophysiological testing system is implemented as a reusable movable unit suitable for repetitive delivery of cells to a disposable, multi-aperture patch-clamp tray. An electric field emanating from the patch aperture is used to align the dispenser with the aperture. A set of electrodes in the nozzle of the dispenser is used to detect the electric field and effect the alignment. According to another aspect of the invention, dielectrophoretic fields produced by sets of electrodes in the nozzle form a retaining cage that is used first to suspend a test cell directly above the patch aperture and then to urge the cell toward it. A movable cell sorter may also be coupled to the cell-delivery unit.Type: GrantFiled: January 9, 2003Date of Patent: June 6, 2006Assignee: Axon Instruments, Inc.Inventors: Yuri Osipchuk, Yuriy Roll, Alan S.

Patent number: 6899800Abstract: A polymeric material such as PDMS is molded into an electrode structure containing a micron-size aperture for receiving and forming a giga-ohm seal with a biological membrane. One end of a tube is filled with uncured polymeric material and pressed against a support surface to prevent drainage. A conventional micropipette having a size suitable for sliding through the tube is introduced, tip first, into the tube and is allowed to fall through the polymeric material and rest against the support surface. The assembly is heated to cure the polymer and the micropipette is removed from the tube, thereby leaving a polymeric plug at the end of the tube with an aperture suitable in shape and size for patch-clamp giga-ohm seal electrode applications. A multi-well tray with a polymeric electrode plug in each well is constructed using the same approach.Type: GrantFiled: June 20, 2002Date of Patent: May 31, 2005Assignee: Axon Instruments, Inc.Inventors: Yuri Osipchuk, Alexei Savtchenko, Alexander A.

Patent number: 6676266Abstract: An optical pathway selector is provided having a first direction selector, a second direction selector, and an actuator. The first direction selector is comprised of a substantially planar member having alternating reflecting and transparent portions. The first direction selector is disposed for rotation on an axle with the substantially planar member positioned askew to a first optical axis. The second direction selector has a configuration similar to that of the first direction selector and is disposed along the axle substantially parallel to the first direction selector. Additional direction selectors can be employed in a similar manner. A motor is connected to the axle for rotating the direction selectors. Alternatively, a motor moves the direction selector along a linear pathway in and out of the pathway of different light beams. The optical pathway selector is used to reflect a beam of light from the first optical axis to alternative optical axes or vice-versa.Type: GrantFiled: October 29, 2001Date of Patent: January 13, 2004Assignee: Axon Instruments, Inc.Inventor: Alexander Dromaretsky

Patent number: 6555802Abstract: A scanning microscope. An objective lens receives light emitted from a sample in object space and propagates it to image space thereof. A collection lens receives light from the objective lens and propagates it to a focal point in image space of the collection lens. A motor has an axis of rotation that is offset from and extends in substantially the same direction as the optical axis. The motor rotates the objective lens about the axis of rotation to scan across a sample in object space of said objective lens. The sample is mounted on a stage. After each rotation of the objective lens, the stage is advanced in a radial direction with respect to the axis of rotation so that each subsequent scan covers a new part of the sample. For fluorescence microscopy, a laser light source is provided. A wavelength-selective beamsplitter directs the laser light toward the objective lens, while allowing fluorescence or reflected light emitted from the sample to pass through to the collection lens.Type: GrantFiled: January 5, 2001Date of Patent: April 29, 2003Assignee: Axon Instruments, Inc.Inventors: Yuri Osipchuk, Alexander Dromaretsky
