Functional Groups

Synonym: EITC. Acceptor fluorophore. Measurement of rotational diffusion of proteins and in fluorescence energy transfer studies: R. Wagner et al.; FEBS Lett. 230, 109 (1988).

Eosin-5-isothiocyanate is a good photosensitizer and can be used to selectively label amines. It has a quantum yield of 0.57 for singlet oxygen generation, which makes it useful for photoconversion of electron-rich materials such as diaminobenzidine (DAB)
