Cy5-PEG-Mal, MW 10K is a compound that belongs to the family of maleimide-activated fluorescent dyes. It consists of three distinct functional groups: Cy5, PEG, and Maleimide. Cy5 is a fluorescent dye that absorbs and emits light at specific wavelengths, making it ideal for visualizing biomolecules in various applications. PEG is a polyethylene glycol chain that is used to increase the solubility and stability of the compound. Maleimide is a reactive group that reacts specifically with sulfhydryl groups (-SH) in proteins, peptides, and other biomolecules.
Cy5-PEG-Mal, MW 10K is extensively used in pharmaceutical research and development due to its ability to selectively label sulfhydryl-containing biomolecules, such as proteins and peptides. This labeling can be used to monitor the distribution and localization of these molecules in vivo and in vitro. Additionally, Cy5-PEG-Mal ,MW 10K has been utilized in drug discovery and development as a tool for characterizing and optimizing the binding interactions between drugs and their protein targets.
