Cy5-PEG-biotin (MW 2000)

Cy5-PEG-biotin (MW 2000) is a polyethylene glycol derivative incorporating a Cy5 fluorescent dye, polyethylene glycol (PEG), and biotin. The Cy5 fluorophore is commonly used in applications such as immunolabeling and nucleic acid labeling. Biotin allows for high-affinity binding with streptavidin or avidin. Cy5-PEG-biotin (MW 2000) plays a crucial role in the specific capture and detection of biomolecules.
