Description

Fluorescein-5-maleimide is an activated fluorescent molecule (excitation: 494 nm, emission: 519 nm) that is used to easily conjugate fluorescein to proteins. The maleimide group reacts optimally with sulfhydryl groups on cysteine side chains at pH 7, forming a stable thioether bond. The compound can be used to label proteins for the detection of conformational changes, assembly of multisubunit complexes, and ligand-binding processes.
