    Product Description

    Cy5-Yne is a clickable azido-reactive fluorescent probe.1 It displays excitation/emission maxima of 650/680 nm, respectively. When conjugated to peptides, Cy5-Yne has been used as a pH-independent fluorescent probe for the activity of lysosomal cathepsin proteases in S. typhimurium-infected and bystander bone marrow-derived macrophages (BMDMs).

    WARNING This product is not for human or veterinary use.
