  • Screening method, screening kit and analysis program
    Patent number: 10031128
    Abstract: A screening method evaluates influence of a cytotoxic factor on lymphoid cells. The method includes administering or irradiating lymphoid cells with the cytotoxic factor that injures the lymphoid cells; incubating the lymphoid cells to which the cytotoxic factor is administered or irradiated for a selected time; measuring a cell size of the lymphoid cells after the incubation; and determining influence of the cytotoxic factor on the lymphoid cells based on a change of the cell size. According to this method, influence of radiation or a drug, or efficacy of radiation, a radiation-protecting agent, an antioxidant, a radiation-sensitizing agent, a drug, or ultraviolet rays can be evaluated economically and objectively in a short period of time.
