Fluorescence Polarization Immunoassay for Rapid, Sensitive Detection of the Herbicide 2,4-Dichlorophenoxyacetic Acid in Juice and Water Samples [PDF]

Biosensors
2,4-Dichlorophenoxyacetic acid (2,4-D) is one of the popular herbicides that is widely used in agriculture and can be found in food and water. A rapid and sensitive fluorescence polarization immunoassay (FPIA) was proposed for the detection of 2,4-D in ...

Fluorescence polarization immunoassay of mycotoxins: a review. [PDF]

Toxins (Basel), 2009
Immunoassays are routinely used in the screening of commodities and foods for fungal toxins (mycotoxins). Demands to increase speed and lower costs have lead to continued improvements in such assays. Because many reported mycotoxins are low molecular weight (below 1 kDa), immunoassays for their detection have generally been constructed in competitive ...

Fluorescence polarization immunoassay of colchicine [PDF]

Journal of Pharmaceutical and Biomedical Analysis, 2018
In this study, a fluorescence polarization immunoassay (FPIA) technique was developed to determine colchicine (COL), an alkaloid of noxious plants of the order Liliales that is used in a number of medications to treat gout. An optimal combination of the polyclonal antibody and the antigen labelled with fluorescein isothiocyanate (FITC) was selected ...

Fluorescence polarization immunoassay for zidovudine [PDF]

Antimicrobial Agents and Chemotherapy, 1989
We report a fluorescence polarization immunoassay (FPIA) for zidovudine (azidothymidine; Retrovir). This assay is accurate and specific over the clinically relevant range of zidovudine concentrations in serum (from 1 to 1,250 ng/ml; from 0.004 to 4.8 microM) and is unaffected by potentially interfering compounds in the sera of patients with renal or ...

Myeloid p38 activation maintains macrophage–liver crosstalk and BAT thermogenesis through IL‐12–FGF21 axis

Hepatology, EarlyView., 2022
Physiological activation of myeloid p38 controls macrophage IL‐12 production and crosstalk to the liver by modulating hepatic FGF21, and subsequently, brown adipose tissue thermogenesis during obesity Abstract Obesity features excessive fat accumulation in several body tissues and induces a state of chronic low‐grade inflammation that contributes to ...

Fluorescence Polarization Immunoassay of Progesterone.

Biological and Pharmaceutical Bulletin, 1997
A homogeneous fluorescence polarization immunoassay (FPIA) was developed to measure levels of progesterone in urine using a TDx analyzer in photocheck mode (Abbott Labs). Two tracers of ethylenediamine fluorescein thiocarbamyl (EDF) were employed; one was synthesized from 11 alpha-hydroxyhemisuccinate progesterone (Prog-11OH-HS) and the other was ...

Clinical evaluation of teicoplanin fluorescence polarization immunoassay [PDF]

Antimicrobial Agents and Chemotherapy, 1991
A teicoplanin fluorescence polarization immunoassay (FPIA) developed by International BioClinical (IBC) was evaluated by using serum samples from patients who had been receiving teicoplanin at Detroit Receiving Hospital (DRH) as part of a clinical investigation.
