The Pikro-Indigocarmine working solution is used for a wide range of applications in scientific research. Especially in histology it is used for selective staining of tissue structures. Its special suitability lies in the unique combination of picric acid and indigocarmine, which offers high sensitivity and specific binding to certain cellular components.

Chemically, the solution consists of aqueous saturated picric acid and indigocarmine. Picric acid is a strong acid and a known fixative, while indigocarmine is an organic dye that produces an intense blue color. The two components interact to form a stable, highly reactive solution.

The way Pikro Indigocarmine Use Solution works is based on the ability of picric acid to fix proteins and other biological molecules, and the ability of indigocarmine to stain specific binding sites. By combining these two components, the solution can be used to visualize specific structures in biological samples, which is critical for diagnostics and life science research.
