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: A cell detection method and a cell detection system capable of performing target cell detection satisfactorily without interference and reducing the time required for detection of target cells are provided. The cell detection method includes a separation step of step S1 to obtain a sample containing target cells by removing at least a part of the non-target cells from a biological sample including target cells and non-target cells based on a difference in forces acting on target cells and non-target cells; a concentration step of step S3 of obtaining a measurement sample having a target cell concentration increased from the sample containing target cells; a detection of step S4 of detecting target cells by subjecting the measurement sample to an imaging flow cytometer.

Abstract: A particle imaging apparatus comprises a flow path comprising a first flow path section, a second flow path section connected downstream of the first flow path section, and a third flow path section that is branched from the first flow path section, a particle detection unit comprising a light source and a light detector, a particle sorting unit configured to adjust a flow direction of the particle, and a particle imaging unit configured to take an image of a particle that flows in the second flow path section. The flow path is structured such that a cross-sectional area of the second flow path section is greater than a cross-sectional area of the first flow path section. The first flow path section and the second flow path section are disposed so as to be linearly aligned.
