Product Data Sheet
Alexa fluor 647 maleimide
Catalog No. A25035
Alexa Fluor 647 maleimide is a far-red-emitting fluorescent dye designed for the selective labeling of protein thiol groups, particularly cysteine residues (Ex/Em = 656/670 nm). This reagent facilitates the attachment of the AF 647 fluorophore to various biomolecules, including proteins, peptides, and thiol-containing oligonucleotides. Its exceptional brightness makes it valuable for applications in cell biology, neuroscience, and disease diagnostics, enabling advanced fluorescence imaging and analysis.
