    7-Hydroxy-2-naphthalene sulfonic acid sodium

    CAS:
    7-Hydroxy-2-naphthalene sulfonic acid sodium (7HNS) is a fluorescent probe that can be used for the detection of cross-links in collagen and elastin. The sensitivity of this compound is very high, with a detection limit of 1 pmol/ml. 7HNS binds to the lysine residues in collagen and elastin, forming covalent bonds that are detectable by fluorescence. It has been used in the analysis of tissues such as cartilage, bone, skin, and blood vessels.
