Patent number: 11213825Abstract: Devices, systems, and methods for en masse patterning of nucleic acid molecule structures are disclosed. The devices can include microchannels and nanoslits. The microchannels and nanoslits can be connected by parking chambers. The systems and methods can utilize the geometry of the devices in coordination with a voltage application routine to park nucleic acid molecules in the parking chambers and subsequently inject the nucleic acid molecules into the nanoslits. The methods can be utilized to present nucleic acid molecules in a fashion suitable for genomic analysis. The methods can also be utilized to provide size selection of the nucleic acid molecules.Type: GrantFiled: May 16, 2018Date of Patent: January 4, 2022Assignees: Wisconsin Alumni Research Foundation, University of Leiden, University of ChicagoInventors: David Charles Schwartz, Kristy L.

Patent number: 9962696Abstract: The present invention relates to phaseguide patterns for use in fluid systems such as channels, chambers, and flow through cells. In order to effectively control filling and/or emptying of fluidic chambers and channels, techniques for a controlled overflowing of phaseguides are proposed. In addition, techniques of confined liquid patterning in a larger fluidic structure, including approaches for patterning overflow structures and the specific shape of phaseguides, are provided. The invention also proposes techniques to effectively rotate the advancement of a liquid/air meniscus over a certain angle. In particular, a phaseguide pattern for guiding a flow of a liquid contained within a compartment is provided, wherein an overflow of the phaseguide by a moving liquid phase is controlled by a local change in capillary force along the phaseguide, wherein said overflow by the liquid over the phaseguide is provoked at the position of the local change in capillary force.Type: GrantFiled: September 22, 2015Date of Patent: May 8, 2018Assignee: UNIVERSITY LEIDENInventors: Paul Vullo, Gerald Urban, Susann Podszun

Patent number: 5554724Abstract: The invention describes peptides derived from tumor rejection antigen precursor MAGE-2. These peptides bind with HLA-A2 molecules, thus presenting complexes which provoke cytolytic T cell production. The resulting "CTLs" are specific for complexes of HLA-A2 and the peptide. The complexes can be used to generate monoclonal antibodies. The cytolytic T cells produced may be used in the context of immunotherapy, such as adoptive transfer.Type: GrantFiled: March 24, 1994Date of Patent: September 10, 1996Assignee: University of LeidenInventors: Cornelis J.
