Patents by Inventor Stevan Jovanovich

Stevan Jovanovich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11231347
    Abstract: A system, methods, and apparatus are described to collect and prepare single cells, nuclei, subcellular components, and biomolecules from specimens including tissues. The system can perform enzymatic and/or physical disruption of the tissue to dissociate it into single-cells or nuclei in suspension or subcellular components including nucleic acids. In some embodiments, the titer of dissociated cells is monitored at intervals and the viability determined. In some embodiments, the processing is adjusted according to the measurements of the titer and viability. In some embodiments, the single-cells or nuclei in suspension are washed and resuspended in the buffer or media of choice. In some embodiments, the conditions are chosen to produce nuclei. In other embodiments, the single-cells or nuclei are purified by affinity paramagnetic bead processing. In some embodiments, matched bulk nucleic acid to the single-cells is produced.

  • Patent number: 6927045
    Abstract: Methods for preparing nanoscale reactions using nucleic acids are presented. Nucleic acids are captured saturably, yet reversibly, on the internal surface of the reaction chamber, typically a capillary. Excess nucleic acid is removed and the reaction is performed directly within the capillary. Alternatively, the saturably bound nucleic acid is eluted, dispensing a metered amount of nucleic acid for subsequent reaction in a separate chamber. Devices for effecting the methods of the invention and a system designed advantageously to utilize the methods for high throughput nucleic acid sequencing reactions are also provided.

  • Publication number: 20050161329
    Abstract: Multi-capillary systems for high-throughput electrophoretic separation and detection of biomolecules are disclosed. One embodiment of the invention uses galactomannans as a size-sieving matrix for multi-channel electrophoretic separations of biomolecules. Multi-color detection for the simultaneous analysis of controls and standards in the same channels as the samples, and endogenous fluorescence detection are also disclosed. Another embodiment of the invention is a two dimensional system for separation of complex samples, using multiplexed capillary electrophoresis system as the second dimension, with a fraction collection step connecting the two separation steps. The systems allow for separations to be accomplished with a highly parallel manner, or in a two-dimensional format.
