Rose bengal lactone (C.I. Solvent Red 141) is a rose bengal lactone stain commonly used to stain the nuclei of plant and animal cells.

Light Green SF Yellowish (Acid Green 5) is an alkaline stain used for staining animal tissues and for cytoplasmic and fiber staining in plant histology.

Phenosafranine, a phenazine dye, exhibits a higher binding affinity for triplex RNA over its parent duplex form, with intercalation as the binding mechanism for both RNA structures. This compound is applicable in staining plant cells and determining levels of hemoglobin, dopamine, serotonin, among other uses [1] [2] [3].

Primulin, a dye known for its ability to visualize plant cell walls, is frequently utilized in botanical studies for detailed observation of cell morphology and structure.

Cellufluor is a fluorescent whitening agent widely used in the textile and paper industries, as well as in biological research. It specifically binds to polysaccharides containing β-1,3 and β-1,4 glycosidic bonds (such as cellulose and chitin), producing strong fluorescence when excited by ultraviolet or short-wavelength visible light, and is used to visualize cell wall structures. In microbiology, Cellufluor enables rapid and sensitive detection of chitin and cellulose in the cell walls of fungi, algae, and plants. Due to the absence of cell wall polysaccharide structures, Cellufluor typically does not stain mammalian cells.
