Description

Basic Orange 21 is a basic dye with a strong orange tint. It has been shown to have good resistance to light exposure and high optical density in low light conditions. Its color can be varied by changing the pH of the medium. Basic Orange 21 also has a particle size that ranges from 2 to 30 nm, which produces an intense red color when exposed to light. The monoclonal antibody against Basic Orange 21 is produced by injection of mice with this dye. Basic Orange 21 has been used as a fluorescent marker for choroidal neovascularization and has been found to be resistant to degradation by matrix effect.
