Product Introduction
ATTO 647 NHS ester is a thiol-reactive fluorophore belonging to the ATTO dye series, characterized by its conjugated aromatic system that enables efficient excitation and emission in the far-red spectrum. The reactive NHS ester functionality allows for covalent coupling with primary amines, making it suitable for labeling proteins and other biomolecules in fluorescence microscopy and flow cytometry applications. This fluorophore exhibits strong photostability and brightness, supporting its use as a reporter molecule in various bioimaging and biosensing workflows.
