Cy3.5-PEG-Mal, MW 2K is a derivative of Cy3.5, a fluorescent dye, which is attached to a PEG (polyethylene glycol) chain, and a maleimide functional group. The maleimide functional group is a highly reactive thiol-reactive group that is used for specific labeling of sulfhydryl-containing biomolecules such as proteins, peptides, and antibodies.
The PEG chain in Cy3.5-PEG-Mal, MW 2K plays a crucial role in enhancing the solubility, stability, and biocompatibility of the compound. The PEG chain also provides a flexible spacer between the fluorescent dye and the reactive maleimide group, enabling efficient conjugation with target biomolecules.
Cy3.5-PEG-Maleimide is used for labeling and tracking biomolecules in drug discovery, pharmacokinetics, and pharmacodynamics studies. Additionally, Cy3.5-PEG-Maleimide is used for the development of diagnostic tools, such as fluorescent imaging, which allows for the visualization and quantification of biological processes in real-time. Moreover, Cy3.5-PEG-Maleimide is employed in the production of therapeutic antibodies and vaccines, enabling the selective modification of target molecules.
