CY5-Duramycin 

Cy5-Duramycin is a fluorescently labeled peptide probe, where duramycin,a 19-amino acid lantibiotic peptide that binds specifically to phosphatidylethanolamine(PE) in cell membranes, is conjugated with the near-infrared dye Cy5 (λ_ex ~650 nm,λ_em ~670 nm). This construct enables highly sensitive optical imaging of PE-rich membranes.
Applications:
Live-cell and tissue imaging of phosphatidylethanolamine distribution.
Apoptosis detection, since PE externalization is a marker of early apoptosis.
Membrane biology studies involving lipid–protein interactions.
Fluorescent probe for diagnostics in cancer, cardiovascular, and neurological research.
