Sulpho MBS is a fluorescent labeling reagent. It is used to label proteins, peptides, and other biomolecules for various experimental applications. The mechanism of action of Sulpho MBS involves the reaction of its sulfonate group with primary amines on the target molecules, forming stable sulfonamide linkages. This covalent modification allows for the visualization and detection of the labeled biomolecules using fluorescence-based techniques. Its mechanism of action at the molecular level involves the specific conjugation of the sulfonate group with the primary amines, resulting in the formation of fluorescent derivatives.
