ABSTRACT
A polarization fluorescence immunoassay (PFIA) for gentamicin with using a set of reagents made in this country was developed. One ml of fluorescein-labeled gentamicin (50 nM) and 100 microliters of antiserum are added to 50 microliters of the sample and the fluorescence polarization is measured. The time of the assay is 10 to 15 minutes, the range of the measurable concentrations is 0 to 800 ng/ml, the sensitivity of the method is 5 ng/ml and the accuracy is 5.8-10.3 per cent. A fluorescence quenching immunoassay (FQIA) for gentamicin was also developed. Determination of gentamicin by the FQIA does not require the use of a specific polarization fluorimeter. Its linear calibrating dependence is more convenient. However, its accuracy and sensitivity are 3 times lower than those of the PFIA.
