Exosome dyes

Exosome dyes are a class of chemical reagents used to label and track cell exosomes. They can specifically bind to exosome surface proteins, lipids or internal components. Through techniques such as fluorescence microscopy, these dyes can help study the secretion, uptake and role of exosomes in intercellular communication.

  • DiI
    T1512941085-99-8
    DiI (DiIC18(3)) is a lipophilic membrane dye commonly used as a long-term tracer for neurons and other cells. DiI fluoresces very weakly before it enters the cell membrane, and only after it enters the cell membrane can it be excited to emit a strong orange-red fluorescence (λex=549 nm, λem=565 nm).
