An immunoassay based on the time-resolved fluorometry (TR-FIA) was developed for microcystins, cyanobacterial peptide hepatotoxins. The assay was performed in a competitive mode and it utilised the monoclonal antibodies raised against microcystin-LR, and a europium chelate of microcystin-LR as a competitive antigen. The sensitivity of the assay was 0.1microg/l. The detection method of TR-FIA was compared to a commercially available kit based on the enzyme-linked immunosorbent assay (ELISA). The same level of sensitivity could be obtained with TR-FIA (in a non-optimised system). The simplified method of TR-FIA leads to a shorter analysis time.
