Descripción

Descripción general

Evans blue (EB) C.I. 23860 is a synthetic bis-azo dye also known as T-1824 and Direct Blue 53. EB dye with higher water solubility has a strong affinity towards serum albumin, making it a high molecular weight protein tracer.

Aplicación

Evans blue is a well-known vital stain with applications in histology and fluorescent microscopy. Evans blue has been used to check cell viability and study blood-brain barrier (BBB) permeability. Additional applications include the demonstration of specific pituitary cell types, selective staining of neutrophil plasma membranes, and fluorescence microscopy as a quenching agent to suppress unwanted autofluorescence.

Acciones bioquímicas o fisiológicas

Evans blue is a non-permeating dye. In presence of plasma membrane damage, the dye enters in the cytoplasm and nucleus, thereby staining them blue. Evans blue is used for checking cell viability. It is also used to study BBB (blood-brain barrier) permeability. The dye binds to albumin and hence indicates BBB breakdown to protein.
