redox indicator

Safranin O (Basic red 2) stains the lignified, embolic and keratinized parts of the plant, as well as chromatin and chromosomes in the nucleus. Safranin O is commonly used for the detection of cartilage, mucin and mast cell granules.

Acid blue is a dark bluish synthetic triphenylmethane dye. It used as a food coloring. The color of the dye is pH-dependent. The structure is also redox-sensitive, changing from a reduced yellow form to an oxidized red form in solution. It is usable as a

DCIP sodium, a blue dye, is commonly utilized in various biochemical and biotechnological applications as an indicator of redox reactions. It possesses unique chemical properties that change color according to the oxidation state of the substance being tested. It is frequently used in enzyme assays, such as measuring succinate dehydrogenase activity, or in protein quantification methods (e.g., the Lowry assay).
