  • Publication number: 20240117423
    Abstract: The invention provides systems and methods for making sequencing libraries that are useful for quantitatively analyzing nucleic acids in a sample. Sample nucleic acids are randomly cleaved at, and PCR handled are attached to, a random cut site. The nucleic acid is amplified into a sequencing library in which a sequencing primer generates a sequence read from adjacent the random cut site. The sequence reads can be mapped to a reference, but they will also include a unique identifier sequence that comes from within the nucleic acid molecule being analyzed, i.e., an intrinsic molecular identifier (IMI). The IMI is unique for each molecule and can thus be used to deduplicate sequence reads originating from the same molecule.

  • Publication number: 20240043940
    Abstract: The disclosure provides methods and systems of analyzing single cells by simultaneously separating cells into monodisperse droplets and tagging each nucleic acid molecule from the cells with barcodes unique to each droplet. The methods and systems combine template particles with a plurality of single cells in a tube, generate in the tube monodispersed droplets encapsulating a single one of the template particles and a single one of the single cells, release nucleic acid molecules from the single cells and provide each nucleic acid molecule with a barcode unique to the respective droplet. The nucleic acid molecules can then be analyzed by any known method, for example by sequencing the nucleic acid molecules.

  • Publication number: 20240024870
    Abstract: Compositions, devices, and methods are disclosed for the modification of polymer surfaces with coatings having a dispersion of silicone polymer and hydrophobic silica. The surface coatings provide the polymer surface with high hydrophobicity, as well as increased resistance to biofouling with proteinaceous material. The polymer surfaces can be particularly useful in microfluidic devices and methods that involve the contacting of the covalently modified polymer surfaces with emulsions of aqueous droplets containing biological macromolecules within an oil carrier phase.

  • Patent number: 11857968
    Abstract: Microfluidic methods of altering the spacing of a stream of objects. In an exemplary method, objects of the object stream may be transported in carrier fluid along a microfluidic channel structure having an inflow region, an outflow region, and an expanded region extending from the inflow region to the outflow region. The expanded region may have a greater cross-sectional area for fluid flow than each of the inflow region and the outflow region. Objects of the object stream may be moved from the inflow region to the expanded region such that at least a subset of such objects are moved closer to one another. Objects of the object stream may be passed from the expanded region to the outflow region to increase a distance between such objects.

  • Patent number: 11827936
    Abstract: This disclosure provides methods and systems for single-cell analysis, including single-cell transcriptome analysis, of target cells without microfluidic devices. The disclosed methods involve the use of template particles to template the formation of monodisperse droplets to generally capture a single target cell from a population of cells in an encapsulation, derive a plurality of distinct mRNA molecules from the single target cell, and quantify the distinct mRNA molecules to generate an expression profile.

  • Publication number: 20230019117
    Abstract: This disclosure provides a decentralized workflow for analyzing single cell gene expression. The workflow makes use of pre-templated instant partitions to segregate cells into separate compartments to individually capture and barcode RNA from single cells in a massively parallel single tube format. The workflow includes steps for processing the RNA from the single cells for sequencing. Separate portions of the decentralized workflow are performed by a research lab and a core facility, allowing increased flexibility in time and location of protocol steps.

  • Publication number: 20230002807
    Abstract: This invention provides ultra-sensitive methods and compositions for detecting patient-specific mutations from cell free nucleic acids (cfDNA) without sequencing. Methods of the invention make use of fluidic partitions for multiplex amplification of cfDNA and thereby create a library of uniformly amplified amplicons. The uniformly amplified amplicons can be split into any number of different detection reactions (while maintaining detection sensitivity) for single-plex detection of mutations present in cfDNA. These methods provide substantially improved signal to noise ratio and easier discrimination of low-abundance mutations.
