Cy3-PEG-biotin (MW 2000)

Cy3-PEG-biotin (MW 2000) is a polyethylene glycol derivative that incorporates Cy3 fluorescent dye, polyethylene glycol (PEG), and biotin. The Cy3 fluorophore is frequently used in applications such as immunolabeling, nucleic acid labeling, fluorescence microscopy, and flow cytometry, with a maximum emission wavelength of approximately 562-570 nm. Biotin in the compound binds with high affinity to streptavidin or avidin. Cy3-PEG-biotin (MW 2000) plays a crucial role in the specific capture and detection of biomolecules.
