System, including methods and compositions, for making and using emulsions that include a silicone oil and a silicone surfactant. The emulsions may include aqueous droplets disposed in a continuous phase that includes a silicone oil and a silicone surfactant. The aqueous droplets may contain an analyte, optionally at partial occupancy, and/or a luminescent (e.g., photoluminescent) reporter. An assay of the analyte may be performed with the droplets. In some cases, signals may be detected from the droplets, and a characteristic of the analyte, such as an analyte level or activity, may be determined based on the signals.

A method for pre-analytical treatment of a serum or plasma sample from a patient suspected of suffering from oxidative stress, which includes contacting the sample with one or more microcapsules having a gelled alginate core and a semipermeable coating, where the alginate core includes dispersed receptors against an oxidised human parathyroid hormone (PTH) peptide. The semipermeable membrane can be obtained by layer-by-layer deposition of polycationic and polyanionic macromolecules onto the gelled core, following by hardening, crosslinking and co-acervation of the macroionic phases.

The present invention relates to hydrogels prepared using silylated organic molecules (such as silylated biomolecules), a process for obtaining the same, and uses thereof.

The present disclosure provides compositions, methods, systems, and devices for polynucleotide processing. Such polynucleotide processing may be useful for a variety of applications, including polynucleotide sequencing.

Methods and systems are provided for isolating fetal cells from a maternal blood supply in order to perform non-invasive prenatal testing. In one example, a system for non-invasive prenatal testing includes a substrate coated with a cell-capturing surface, the cell-capturing surface including an array of pillar-like structures, each pillar-like structure including a plurality of intersecting arms.

The present invention provides a method for diagnosing or determining a pancreatic cancer-associated disease state comprising or consisting of the steps of: (a) providing a sample from an individual to be tested; and (b) determining a biomarker signature of the test sample by measuring the presence and/or amount in the test sample of one or more biomarker selected from the group defined in Table A; wherein the presence and/or amount in the test sample of the one or more biomarker selected from the group defined in Table A is indicative of the pancreatic cancer-associated disease in the individual; uses and methods of determining a pancreatic cancer-associated disease state, and methods of treating pancreatic cancer, together with arrays and kits for use in the same.

The present invention is drawn to the generation of micropatterns of biomolecules and cells on standard laboratory materials through selective ablation of a physisorbed biomolecule with oxygen plasma. In certain embodiments, oxygen plasma is able to ablate selectively physisorbed layers of biomolecules (e.g., type-I collagen, fibronectin, laminin, and Matrigel) along complex non-linear paths which are difficult or impossible to pattern using alternative methods. In addition, certain embodiments of the present invention relate to the micropatterning of multiple cell types on curved surfaces, multiwell plates, and flat bottom flasks. The invention also features kits for use with the subject methods.

A method for sensing an analyte uses tethered particle motion. A functionalized particle has a first state in which the functionalized particle is bound to the surface and a second state in which the functionalized particle is not bound to the surface, where the functionalized particle switches between the first and second states depending on the presence and absence of the analyte, thereby changing motion characteristics of the functionalized particle depending on the presence of the analyte. A spatial coordinate parameter of the functionalized particle is measured by a detector, and a processor determines the presence/concentration of the analyte from changes in the measured spatial coordinate parameter.

An immunoadsorbent and a composite affinity column for purifying fumonisin B1, anguidin, T-2 toxin, zearalenone, and vomitoxin. The immunoadsorbent includes a solid phase carrier, and a fumonisin B1 monoclonal antibody, an anguidin monoclonal antibody, a T-2 toxin monoclonal antibody, a zearalenone monoclonal antibody and a vomitoxin monoclonal antibody which are coupled to the solid phase carrier, the anguidin monoclonal antibody is a monoclonal antibody secreted by a hybridoma cell strain DAS5G11E7 having an accession number of CCTCCNO:C201881. The affinity column can be used for high performance liquid chromatography-mass spectrometry detection of the fumonisin B1, the anguidin, the T-2 toxin, the zearalenone and the vomitoxin, and has stable performance. Furthermore, an economical, quick, precise and safe detection method is established of the basis of the affinity column, and can be used for purifying and detecting samples of the five toxins without mutual interference and influence.

A cerasome delivery system for targeting activated cd44 molecule, a preparation method and use thereof: a surface of a cerasome is partially modified by a targeting ligand, the targeting ligand being a ligand which may specifically bind to an activated cd44 molecule. The cerasome delivery system may be used for the diagnosis, prevention and treatment of vulnerable plaque or diseases associated with vulnerable plaque.
