Abstract: In one aspect, the present teachings provide a system for performing cytometry that can be operated in three operational modes. In one operational mode, a fluorescence image of a sample is obtained by exciting one or more fluorophore(s) present in the sample by an excitation beam formed as a superposition of a top-hat-shaped beam with a plurality of beams that are radiofrequency shifted relative to one another. In another operational mode, a sample can be illuminated successively over a time interval by a laser beam at a plurality of excitation frequencies in a scanning fashion. The fluorescence emission from the sample can be detected and analyzed, e.g., to generate a fluorescence image of the sample. In yet another operational mode, the system can be operated to illuminate a plurality of locations of a sample concurrently by a single excitation frequency, which can be generated, e.g., by shifting the central frequency of a laser beam by a radiofrequency.

Abstract: A screening method is provided. Cells secreting target antibodies are screened by mixing candidate cells labeled with a first fluorescent molecule, a capture antigen and a labeled antibody against a target antibody and incubating, labeling using a high content cell imager and sorting using flow cytometry so as to screen cells secreting target antibodies. The screening method disclosed in the present application can automatically complete the labeling and sorting of target candidate cells in high throughput by labeling with a fluorescent molecule in combination with high-content cell imager and flow cytometer, so as to provide sufficient quantity of cells for subsequent amplification to obtain their antibody sequences and screen affinity antibodies. This method greatly improves the screening efficiency.
