Patent number: 10500585Abstract: The present invention provides methods, systems, assemblies, and articles for extracting restrained liquid (e.g., surface tension-restrained liquid) from open wells in a chip, where the restrained liquid does not flow out of the wells due to gravity when the wells are held upside down. For example, the present invention provides extraction fixtures that may be attached to, and/or held adjacent to, a chip such that any restrained liquid that is forced out of the open wells is collected by, or flows through, the extraction fixtures. Also for example, the present invention provides assemblies composed of a extraction fixture attached to, and/or held adjacent to, a chip, and methods of subjecting such assemblies to a force such that at least a portion of the restrained liquid in the open wells is forced out and collected by, or flows through, the extraction fixture.Type: GrantFiled: September 19, 2016Date of Patent: December 10, 2019Assignee: TAKARA BIO USA, INC.Inventors: Bradley L.
