AF430 is a fluorescent dye structurally and functionally analogous to Alexa Fluor™ 430, which belongs to the popular Alexa Fluor™ family of fluorescent dyes. Its excitation maximum is at 431 nm, emission maximum is at 540 nm, and Stokes shift is 109 nm. Like Alexa Fluor™ 430, AF430 exhibits high photostability and pH-insensitive fluorescence. The dye can be excited by 405 nm violet laser or 445 nm laser.
AF430 carboxylic acid is a non-reactive form of AF430 dye that can be used for the analysis of labeled samples — as a reference standard in procedures where AF430 dye conjugates are involved.
