Description

Cy5-PEG-MAL (Cy5-PEG-Maleimide) refers to a chemical compound or conjugate that includes Cy5 (a cyanine-based fluorescent dye), polyethylene glycol (PEG), and a maleimide (MAL) functional group. Cy5 is a member of the cyanine dye family known for its strong near-infrared fluorescence. It is widely used in molecular and cellular imaging applications due to its favorable properties, including high quantum yield and photostability. The maleimide group is a reactive functional group that selectively reacts with thiol (sulfhydryl) groups, forming stable thioether bonds. This maleimide-thiol reaction is commonly used in bioconjugation to attach fluorophores, labels, or other molecules to proteins, peptides, or other thiol-containing biomolecules.
