Eosin-Phloxin Solution S is a common histological staining solution used in numerous microscopic examinations. It enables a differentiated view of cell and tissue structures due to the specific binding of the two dyes it contains, eosin and phloxin.

Eosin is an acidic dye and therefore binds preferentially to basic components in cells and tissues, especially proteins such as hemoglobin and muscle proteins. It produces a strong red coloration that stands out excellently from other colors and therefore provides excellent contrast.

Phloxin is also an acidic dye and shows a strong affinity for basic structures, especially cell nuclei and nucleic acids. It produces intense staining that allows clear delineation of cell nuclei and accurate identification of cell types.

The combination of eosin and phloxin in a single solution therefore provides comprehensive and differentiated visualization of cells and tissues. This is particularly critical in histopathology diagnostics and research, where accurate identification and characterization of cells and tissues is necessary for the detection and evaluation of disease and pathological changes. Eosin-Phloxin Solution S is therefore an indispensable tool in modern histological analysis.
