Cy5-PEG-Mal, MW 2K contains a Cy5 fluorescent dye that emits red light upon excitation, making it useful for labeling proteins, nucleic acids, and other biological molecules. It also has a PEG (polyethylene glycol) linker, which imparts water solubility and biocompatibility to the compound, making it suitable for use in biological systems.
Furthermore, the compound contains a maleimide functional group, which allows it to selectively react with thiol groups on cysteine residues in proteins, forming a stable thioether linkage. This property makes it a valuable tool in protein modification, conjugation, and crosslinking applications.
Cy5-PEG-Mal, MW 2K is often used for protein labeling, site-specific conjugation, and the detection and quantification of proteins in biological samples. It is also used in drug discovery and development for the study of protein-protein interactions and the screening of potential drug candidates.
