High Efficiency, Large Field Scanning Microscope

View page
US Patent:
6833916, Dec 21, 2004
Filed:
Sep 4, 2003
Appl. No.:
10/656728
Inventors:
Yuri Osipchuk - Foster City CA
Sasha Dromaretsky - Davis CA
Yuriy Roll - Foster City CA
Stephen Smith - Los Altos CA
Assignee:
Axon Instruments, Inc. - Foster City CA
International Classification:
G01N 2164
US Classification:
356318, 356417, 2504581
Abstract:
A fluorescent optical imaging system ( ) produces two separate spots (S and S ) on a sample ( ) by a pair of excitation laser beams (B and B ) that are generated by first and second lasers (L and L ). Excitation laser beams (B and B ) pass at slightly different angles, first through an aperture ( ) of a 45Â fold mirror ( ), and then through an objective element ( ). As a result, emission light beams ( ) are generated from each illuminated spot (S and S ) and are reflected and redirected by mirror ( ) through a secondary lens ( ) before reaching one of two detectors (PMT and PMT ). Emission beam ( ) reflects off a second 45Â mirror ( ) prior to reaching detector (PMT ), while emission beam ( ) travels directly to (PMT ). If desired, optical separation elements ( ), such as dichroic filters, prisms, or gratings, can be positioned in front of each detector (PMT and PMT ). Fluorescent optical imaging system ( ) may employ a scanning system ( ) for illuminating and imaging the entire area of sample ( ).

Detachable Cell-Delivery System For Patch-Clamp Unit

View page
US Patent:
7056430, Jun 6, 2006
Filed:
Jan 9, 2003
Appl. No.:
10/339142
Inventors:
Yuri Osipchuk - Foster City CA, US
Yuriy Roll - Foster City CA, US
Alan S. Finkel - E. Malvern, AU
Alexander A. Dromaretsky - Davis CA, US
Branko Bem - Newark CA, US
Assignee:
Axon Instruments, Inc. - Union City CA
International Classification:
G01N 33/487
US Classification:
2057775, 205792, 20440301, 204547, 204643, 4352871
Abstract:
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.
