Application

Lissamine Green B has been used in blood-brain barrier (BBB) studies and is used to study the its effect on herpes simplex virus 1 (HSV-1) corneal infection in animals.

Biochem/physiol Actions

Lissamine green also referred to as acid green 50, wool green S, food green S or green S, is used for vital staining of cornea and conjunctiva. Staining characteristics are almost similar to rose bengal dye. Lissamine green is also used to stain membrane-damaged epithelial cells. In vitro, Lissamine green B at low concentration blocks herpes simplex virus 1 (HSV-1) plaque formation.

Differentiation of metazoan cells requires execution of different gene expression programs but recent single-cell transcriptome profiling has revealed considerable variation within cells of seeming identical phenotype. This brings into question the relationship between transcriptome states and cell phenotypes. Additionally, single-cell
