Description générale

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.

The plant vascular network consists of specialized phloem and xylem elements that undergo two distinct morphogenetic developmental programs to become transport-functional units. Whereas vacuolar rupture is a determinant step in protoxylem differentiation, protophloem elements never form a big central vacuole.
