A direct and continuous kinetic method for the fluorimetric assay of various hydrolases by using new, highly water-soluble substrates is described. The latter consist of esters of strongly fluorescent 1-hydroxypyren-3,6,8-trisulfonic acid trisodium salt with acetic, butyric, caprylic, and oleic acid.
