[Polarized immunofluorescent analysis of the herbicide isoproturon]. / Poliarizatsionnyi fliuoroimmunoanaliz gerbitsida izoproturona.

Polarographic fluoroimmunoassay was developed for estimation of residual amounts of the herbicide isoproturon . The procedure is simple, accurate, highly sensitive and allows 10 preparations to be tested within approximately 7 min; the sample volume was 50 microliters and the low limit of the procedure sensitivity was about 0.2 micrograms/ml. The polarographic immunoassay may be used in screening express controls of isoproturon concentration in the sewage or in various extracts from various sources to control the herbicide contamination.

[Development of a method of polarization fluorescence immunoanalysis of the herbicide 2,4,5-trichlorophenoxyacetic acid]. / Razrabotka poliarizatsionnogo fliuorestsentnogo immunoanaliza gerbitsida 2,4,5-trikhlorfenoksiuksusnoi kisloty.

Immunoreagents were produced and a polarographic fluorescent immunoassay was developed for estimation of residual content of widely used herbicide 2,4,5-trichlorophenoxy acetic acid. The procedure is simple, accurate, specific and allowed one to measure 10 preparations within 7 min. The sample volume was 50 microliters and the minimal content of the substance estimated was 0.5 microgram/ml. This procedure may be used in screening quick tests of the herbicide concentration in sewage or in extracts from various sources.
