Cy5.5-PEG-NH₂ is a fluorescent PEG derivative that combines the near-infrared Cy5.5 dye with a PEG spacer and a terminal amine group. With an emission maximum around 710 nm, Cy5.5 enables sensitive detection with low background, making this conjugate well-suited for fluorescence imaging, immunolabeling, nucleic acid labeling, microscopy, and flow cytometry. The PEG spacer improves water solubility and biocompatibility, while the amino group allows straightforward conjugation to biomolecules or surfaces.

Biopharma PEG supplies high-purity Cy5.5-PEG-NH₂ in defined molecular weights, from research scale to GMP-grade production, with reliable batch consistency to support advanced imaging and labeling applications.
