The L5178Y TK+/- mouse lymphoma assay is widely used in mutagenicity testing. Trifluorothymidine-resistant (TFTr) mutants are quantitated following growth in agar-supplemented cloning medium. In an attempt to evaluate the effect of agar on plating efficiency, we have tested several lots
A laccase-mediator system (LMS) for biobleaching was applied to a bleached chemical pulp dyed with stilbene dye Direct Yellow 11. Of mediators tested, 2,2'-azinobis(3-ethylbenzthiazoline-6-sulfonate) (ABTS) was found to be more effective than either violuric acid (VA) or N-hydroxybenzotriazole (HBT), which
Food analysis demands fast methods for routine control and high throughput of samples. Chromatographic separation enables simultaneous determination of numerous compounds in complex matrices, several approaches increasing separation efficiency and speed of analysis were involved. In this work, modern types

The disposition of 2-(2-quinolyl)-1,3-indandione (D. C. yellow #11, DCY) in male Fischer rats dosed intravenously or by feeding was determined. For rats given [14C]DCY in the feed (0.00044-0.41% of the diet), recovery of radioactivity during the 24-h dosing period and
The certified drug and cosmetic dye substance known as D & C Yellow No. 11 [2-(2-quinolyl)-1,3 indandione] was tested for its dermal sensitization potential in guinea pigs. An induction regimen consisting of a single footpad injection of Complete Freund's Adjuvant
