AFDye-488-Maleimide (Alexa Fluor-488-Maleimide equivalent) is a type of fluorescent dye that is composed of several functional groups. The AFDye-488 group is a fluorophore that can be used to label proteins and other biomolecules for fluorescence imaging and analysis. The maleimide group is a reactive functional group that can form a covalent bond with a thiol group on a biomolecule.
In practice, AFDye-488-Maleimide (Alexa Fluor-488-Maleimide equivalent) is often used to label proteins for use in fluorescence microscopy and flow cytometry experiments. The maleimide group on the dye is reactive towards thiol groups on cysteine residues in proteins, allowing it to be covalently attached to the protein of interest. Once labeled with AFDye-488-Maleimide (Alexa Fluor-488-Maleimide equivalent), the protein can be visualized and quantified using fluorescence imaging techniques.
