Alexa fluor 647 maleimide [CAS 1825332-75-9]

Alexa fluor 647 maleimide is a bright, far-red-emitting fluorescent dye for labeling of protein SH groups (Ex/Em = 656/670 nm) . Alexa fluor 647 maleimide can be used to attach AF 647 fluorophore to proteins and peptides containing cysteine residues, as well as to other thiolated molecules (such as thiol-containing oligonucleotides) . Alexa Fluor 647 maleimide is promising for research of cell biology, neuroscience, and disease diagnostics[1][2].
