AF430 is a stable dye over the broad pH range (from 4 to 10) with a maximum fluorescence in the yellow-green spectrum (at 542 nm). AF430 is absolutely similar to Alexa Fluor™ 430 dye by its spectral characteristics.
Biomolecules conjugates with AF430 can be used in flow cytometry, for example in multicolor staining. AF430 is also used in cell microscopy due to its high photostability.
AF430 amine is soluble in water and can be conjugated with electrophiles and participate in enzymatic transamination.
