英文摘要a sensitive homogenous time-resolved fluoroimmunoassay (tr-fia) method for bensulfuron-methyl (bsm) based on fluorescence resonance energy transfer (fret) from a tb3+ fluorescent chelate with n,n,n',n'-[2,6-bis(3'-aminomethyl-1'-pyrazoly)-4-phenylpyridine] tetrakis(acetic acid) (bpta-tb3+) to organic dye, cy3 or cy3.5 has been developed. new method combined the use of bpta-tb3+ labeled streptavidin, cy3 or cy3.5 labeled anti-bsm monoclonal antibody and biotinylated bsm-bsa conjugate (bsa is bovine serum albumin) for competitive-type immunoassay. after bpta-tb3+ labeled streptavidin was reacted with a competitive immune reaction solution containing biotinylated bsm-bsa, bsm sample and cy3 or cy3.5 labeled anti-bsm monoclonal antibody, the sensitized and long-lived emission of cy3 or cy3.5 derived from fret was measured, and thus the concentration of bsm in sample was calculated. the present method has the advantages of rapidity, simplicity and high sensitivity since the b/f (bound reagent/free reagent) separation steps and the solid-phase carrier are not necessary. the method gives the detection limit of 2.10 ng ml(-1). the coefficient variations of the method are less than 1.5% and the recoveries are in the range of 95-105% for bsm water sample measurement.
