Apparatus and method for real-time measurement of cellular response

(57) It is mixed with the examination compound (303) of concentration with the homogeneous suspension (349) of each portion contained in the cell type of a summary series, . It is led to a detection zone (355), and also the cell response of the cell which was useful when the cell in an examination mixture passed through and flowed through a detection zone (355) is measured in real time. The equipment and the method for measuring the cell response of the examination compound to the cell suspension (349) which is flowing, or a series of examination compounds (303) in real time. This equipment is applicable to automatic screening of the library of a compound, and can change the concentration of an examination compound and a standard compound in real time, and also can generate dosage / reaction profile for a short time.
