General description

Calcofluor White Stain (C.l. 40622) is a stilbene compound that has additional triazinyl and phenyl aromatic groups. It is also known as cellufluor.

Application

Calcofluor White Stain is a fluorescent stain that is used for the rapid detection of yeasts, fungi, and parasitic organisms. It is a non-specific fluorochrome that binds to cellulose and chitin in cell walls. It is suitable for use as a viability stain for plant cells. Additionally, calcofluor white is recommended as a counterstain for in situ hybridization staining of plant material and as a flow cytometry stain for assessing the viability of animal cells.
