Product Introduction
ATTO 633 NHS ester is a reactive fluorescent dye belonging to the ATTO dye series, characterized by its sulfonated rhodamine core, which provides high photostability and strong fluorescence. It features an N-hydroxysuccinimide (NHS) ester group, enabling efficient conjugation to primary amines found in proteins, peptides, and other biomolecules, facilitating covalent labeling. This fluorophore exhibits excitation and emission maxima suitable for red spectral region applications, making it a valuable component in fluorescence microscopy, flow cytometry, and FRET-based assays.
