TL;DR: A flow-through membrane-based enzyme immunoassay for the rapid detection of ochratoxin A in wheat was developed and showed the most intense blue color because of the inverse relationship between toxin concentration and color development.

TL;DR: In this article, Folin-Ciocalteu phenol reagent was used in the Somogyi-Nelson method to remove the toxic arsenic compounds from the color reaction system.
Abstract: Nelson’s arsenomolybdate, the chromogenic reagent in Somogyi–Nelson method, was replaced by Folin–Ciocalteu phenol reagent. The major object was to remove the toxic arsenic compounds from the color reaction system. The color-producing ability of the phenol reagent was considerably lower than that of Nelson’s reagent. However, the modified method was favorably comparable to Somogyi–Nelson method in simplicity, reproducibility and stability of color development. The error in both the modified and Somogyi–Nelson method could be reduced to about one fourth by adding sodium benzoate (final concentration, about 0.5%) to the test solutions.

TL;DR: In this paper, a band of material giving the 3β-hydroxy- Δ 5 steroid reaction with antimony trichloride staining reagent and previously named "U 2 " was purified by further thin-layer chromatography and identified as 16β -hydroxydehydroepiandrosterone.
