Rapid and sensitive detection of tert-butylhydroquinone in soybean oil using a gold-based paper sensor

Abstract

Tert-butylhydroquinone (TBHQ) residues in foods pose a threat to human health. Therefore, it is necessary to develop a rapid method for TBHQ detection. In this study, a sensitive monoclonal antibody...

Hapten synthesis and a colloidal gold immunochromatographic strip assay to detect nitrofen and bifenox in fruits

“…These nanoparticles form stable colloidal suspensions under electrostatic action, and can then be used to label the selected monoclonal antibody proteins (GNP-labeled mAbs). The synthesis of the two substances was performed as described in the research by Xu et al 28…”

Preparation of a broad-specific monoclonal antibody and development of an immunochromatographic assay for monitoring of anthranilic diamides in vegetables and fruits

“…The affinity constant ( K aff ) of mAb was measured using indirect ELISA according to our previous report. 36…”

“…The affinity constant (K aff ) of mAb was measured using indirect ELISA according to our previous report. 36 Standard solutions were serially diluted in a 3-fold gradient and analyzed using ic-ELISA. The original concentrations of CHL, CYA, CYC, and TEA were 2, 2, 4, and 5.4 ng mL −1 , Fig.…”

Fluorescent strip sensor for rapid and ultrasensitive determination of fluoroquinolones in fish and milk

“…Finally, the mAb against FQs was prepared by injecting the cells into the abdominal cavity of mice and purifying ascites fluid using the precipitation method of caprylic acid and saturated ammonium sulfate. 38 The prepared mAb was stored at 4 °C for further use.…”
