Description

General description

Nile Blue A is aminodiethylaminonaphthophenoxazonium sulfate employed in biology and histology. It is a highly fluorescent, and photostable organic dye used to dye clothing, and is for use in lipid histochemistry.

Application

Nile blue A is suitable for staining and discriminating between melanins and lipofuscins in paraffin sections of animal tissue, and in a histochemical method for lipids in frozen sections.

Biochem/physiol Actions

Nile blue A stains acidic components, such as phospholipids, nucleic and fatty acids by imparting a dark blue color, while neutral lipids, namely triglycerides, are stained pink, or red.

Features and Benefits

Used in the preparation of an amperometric glucose sensor.
