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.

We have determined the complete genome sequences of a host-promiscuous Salmonella enterica serovar Enteritidis PT4 isolate P125109 and a chicken-restricted Salmonella enterica serovar Gallinarum isolate 287/91. Genome comparisons between these and other Salmonella isolates indicate that S. Gallinarum 287/91 is

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.

Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops such as wheat, barley, and maize. Both sexual (ascospores) and asexual (conidia) spores are produced in F. graminearum. Since conidia are responsible for secondary infection in

Invasive aspergillosis (IA) is a common and life-threatening infection in immunocompromised individuals. A number of environmental and epidemiologic risk factors for developing IA have been identified. However, genetic factors that affect risk for developing IA have not been clearly identified.
