Filed:

Jul 12, 2013

Appl. No.:

13/940424

Inventors:

Igor Y. Khandros - Orinda CA, US
Gaetan L. Mathieu - Varennes, CA
Steven W. Short - Pleasanton CA, US
Ming C. Wu - Moraga CA, US

International Classification:

C12N 13/00

US Classification:

435450, 4351731, 4352831, 4351736

Abstract:

Two or more biological micro-objects can be grouped in a liquid medium in a chamber. Grouping can comprise bringing into and holding in proximity or contact the micro-objects in a group, breaching the membrane of one or more of the micro-objects in a group, subjecting one or more of the micro-objects in a group to electroporation, and/or tethering to each other the micro-objects in a group. The micro-objects in the group can then be combined into a single biological object.

Abstract:

Biological activity in holding pens in a micro-fluidic device can be assayed by placing in the holding pens capture objects that bind a particular material of interest produced by the biological activity. The biological material of interest that binds to each capture object can then be assessed, either in the micro-fluidic device or after exporting the capture object from the micro-fluidic device. The assessment can be utilized to characterize the biological activity in each holding pen. The biological activity can be production of the biological material of interest. Thus, the biological activity can correspond to or arise from one or more biological cells. Biological cells within a holding pen can be clonal cell colonies. The biological activity of each clonal cell colony can be assayed while maintaining the clonal status of each colony.

International Classification:

B01L 3/00
G01N 33/558

Abstract:

A microfluidic device can comprise at least one swept region that is fluidically connected to unswept regions. The fluidic connections between the swept region and the unswept regions can enable diffusion but substantially no flow of media between the swept region and the unswept regions. The capability of biological micro-objects to produce an analyte of interest can be assayed in such a microfluidic device. Biological micro-objects in sample material loaded into a microfluidic device can be selected for particular characteristics and disposed into unswept regions. The sample material can then be flowed out of the swept region and an assay material flowed into the swept region. Flows of medium in the swept region do not substantially affect the biological micro-objects in the unswept regions, but any analyte of interest produced by a biological micro-object can diffuse from an unswept region into the swept region, where the analyte can react with the assay material to produce a localized detectable reaction. Any such detected reactions can be analyzed to determine which, if any, of the biological micro-objects are producers of the analyte of interest.

International Classification:

B01L 3/00
B03C 5/02
B03C 5/00

Abstract:

A structure for providing a boundary for a chamber in a microfluidic apparatus can comprise dielectrophoresis (DEP) configurations each having an outer surface and electrowetting (EW) configurations each having an electrowetting surface. The DEP configurations can facilitate generating net DEP forces with respect to the outer surfaces of the DEP configurations to move micro-objects on the outer surfaces, and the EW configurations can facilitate changing wetting properties of the electrowetting surfaces to move droplets of liquid medium on the electrowetting surfaces.
