This product is lectin PNA labeled with our superior green fluorescent dye CF488A. Lectin PNA is specific for terminal β-galactose and binds preferentially to a commonly occurring structure, galactosyl (β-1,3) N-acetylgalactosamine. CF488A (Ex/Em = 490/515 nm) is a superior alternative to the traditional green fluorescent dye FITC (or fluorescein) owing to its exceptional brightness and photostability. CF488A has brightness and photostability comparable to Alexa Fluor? 488.
