Aniline Blue-Gold Orange is a combination of two dyes used in histology and cytology for staining cell preparations and tissue sections. Aniline blue is a basic dye that binds to acidic cellular components, such as collagen fibers and mucopolysaccharides, giving them a blue color. Gold orange is an acidic dye that binds to basic cellular components, such as proteins, giving them an orange color.
The combination of aniline blue and gold orange allows differentiated staining of various cell and tissue structures, facilitating detailed examination under the microscope and enabling identification of different cell types and morphological changes. Aniline blue-gold orange staining can be used in various histological and cytological staining protocols to improve differentiation and characterization of various tissue structures.
