Abstract: Methods and kits for accurately detecting one or more analytes in a sample by removing non-specific binding signals utilizing capture and control microparticles. The capture microparticles can specifically bind to the analyte while the control microparticles do not specifically bind to the analyte but to the background molecules. Both capture and control microparticles are added to the sample under suitable conditions to allow binding between analytes and the microparticles. Detection agent is then added to bind to analytes and other substances captured by the microparticles. The microparticles are then run through a cytometry-based detection method, where detection signals from the capture and the control microparticles are distinguished.

Abstract: A measurement system includes a system for causing relative motion between a sample and an irradiation spot. The sample includes fluorescent markers having respective wavelengths. A gating system provides a gating signal based at least in part on resultant light substantially at an irradiation wavelength. A detection system detects fluorescent light from the irradiated markers and provides detection signals representing the fluorescent light detected concurrently with a gate-open signal. In some examples, the detection system detects fluorescent light at multiple wavelengths and provides respective detection signals. A spectral discriminator arranged optically between the sample and the detection system receives the fluorescent light from the sample and provides respective fluorescent light at the wavelengths to the detection system. A flow cytometer can spectrally disperse resultant fluorescent light and measure the wavelengths separately.

Abstract: Disclosed is a method for measuring an immunostimulatory response of an immune cell, including (i) bringing a measurement target immune cell into contact with an immunostimulator, (ii) forming a contact surface with a substance different from the measurement target immune cell on the measurement target immune cell, (iii) bringing the measurement target immune cell into contact with a capturing body that binds to a surface antigen on the contact surface and is capable of generating an optical signal, (iv) detecting the optical signal generated from the capturing body, and (v) determining whether or not the measurement target immune cell from which the contact surface has been eliminated before detecting the optical signal has an immunostimulatory response, based on the detected optical signal.

Abstract: The present disclosure relates to a method for identifying cells that express antigen-specific antibodies with a high binding affinity for a monomeric antigen. Using fluorescence activated cell sorting, cells expressing high affinity antigen-specific antibodies are selected from a population of immune cells isolated from a mammal that has been immunized with or otherwise exposed to the antigen. Nucleic acids encoding the high affinity antibodies can then be cloned into other lymphoid and non-lymphoid cells where the antibody can be expressed and from which the antibodies can be secreted.

Abstract: The invention provides a method for preparing an expanded renal (kidney) tissue sample suitable for microscopic analysis. Expanding the kidney sample can be achieved by binding, e.g., anchoring, key biomolecules to a polymer network and swelling, or expanding, the polymer network, thereby moving the biomolecules apart as further described herein. As the biomolecules are anchored to the polymer network, isotropic expansion of the polymer network retains the spatial orientation of the biomolecules resulting in an expanded, or enlarged, kidney sample.

Systems and kits for practicing the subject methods are also provided.
