AF488 NHS ester (TEA)
AF488 NHS ester TEA is an amine specific fluorescence probe (λem=525 nm=525 nm). AF488 NHS ester reacts with sulfhydryl groups and amines in aqueous and biological samples then change their chemical structure and fluorescence properties after derivatization. AF488 exhibits the λem and λex wavelength of 520 nm and 470 nm, respectively.
