AFDye-488-TFP ester (Alexa Fluor-488-TFP ester equivalent) CAS:2133404-55-2 is a fluorescent dye that is commonly used in biological research applications. It is composed of several functional groups, including an AFDye-488 fluorophore, a TFP (tetrafluorophenyl) ester group, and an additional ester group.
The AFDye-488 fluorophore is a green-fluorescent dye that can be used to label proteins, antibodies, and other biomolecules for use in imaging and detection applications. The TFP ester group is a reactive functional group that can be used to covalently attach the dye to specific sites on proteins or other biomolecules. This allows for specific targeting and imaging of those molecules. The additional ester group can also be used in certain reactions to modify the dye or its attachment to biomolecules.
