Abstract
An automatic immunoassay apparatus utilizes cartridges each having at least two wells, a first well of said wells containing solid phase material carrying antigen or antibody, a second well of said wells containing antibody or antigen labelled with labelling compound. The wells may be sealed with a suitable sealing film before use and the sealing film is broken when the cartridge is to be used. The cartridges are transported to a predetermined position on a steppingly movable reaction line and conveyed thereby at a predetermined interval. While the reaction line steps, a sample, labelled antigen or antibody contained in the second well and substrate, if necessary, are added to the first well and stirred at predetermined timings and reaction between the sample and a reactive solution is measured under control of a control device having memory means storing operator selectable programs for various measuring methods.
