Water-soluble azo, phthalein, sulphonphthalein and anthraquinone indicators and reagents were subjected to low-voltage electrophoresis on cellulose acetate sheets at pH 2–12. All dyes except low-sulphonated azo dyes yielded one or more sharp bands showing good mobility and resolution over some range of pH values.

Singlet Oxygen in Plants—Its Significance and Possible Detection with Double (Fluorescent and Spin) Indicator Reagents [PDF]
Photochemistry and Photobiology, 2006 ABSTRACTDirect detection of reactive oxygen species (ROS), especially singlet oxygen, in plants under stress conditions is of special importance, not only to identify primary events of oxidative damage, but also in studies exploring the potential role of ROS as signal molecules.

Complexometric titrations: new reagents and concepts to overcome old limitations.
In Analysis, 2016Chelators and end point indicators are the most important parts of complexometric titrations. The most widely used universal chelator ethylenediamine tetraacetic acid (EDTA) and its derivatives can strongly coordinate with different metal ions.
