Fluorescence Polarization-Based Bioassays: New Horizons

Sensors, 2020
Fluorescence polarization holds considerable promise for bioanalytical systems because it allows the detection of selective interactions in real time and a choice of fluorophores, the detection of which the biosample matrix does not influence; thus ...

Automated fluorescence polarization immunoassay for monitoring streptomycin [PDF]

Antimicrobial Agents and Chemotherapy, 1983
The fluorescence polarization immunoassay technique has been used previously for the assay of vancomycin and the aminoglycoside antibiotics (gentamicin, tobramycin, and amikacin). We extended this technique to assay streptomycin. Fluorescein-labeled streptomycin was used as the tracer, and antiserum specific for streptomycin was raised in rabbits by ...

Rapid and homologous immunoassay for the detection of herbicide propisochlor in water

Food and Agricultural Immunology, 2018
The herbicide propisochlor can be introduced into the water cycle via agricultural activities, thus possibly leading to harmful ecological effects. It is significant for the development of a rapid method for propisochlor analysis in water.
