ABSTRACT:
An automatic immunoassay apparatus utilizes cartridges each having at least two wells, a first well containing solid phase material carrying antigen or antibody, and a second well 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 reactions between the sample and a reactive solution are measured under control of a control device having a memory storing operator selectable programs for various measuring methods.
