  • Title: [Studies on the complete enzymatic hydrolysis of steroid conjugates in urine (author's transl)].
    Author: Graef V, Fuchs M.
    Journal: Z Klin Chem Klin Biochem; 1975 Apr; 13(4):163-7. PubMed ID: 125492.
    Abstract:
    The incubation of urine with beta-glucuronidase/arylsuphatase from Helix pomatia results in the incomplete hydrolysis of urinary steroid conjugates, because inhibitors of these enzymes are present in urine; The inhibitors can be separated from the steroid conjugates by chromatography of the urine on a column of Amberlite XAD-2. By this method a complete enzymatic hydrolysis of urinary steroid conjugates is possible in 24 hours at 37 degrees C or in 2 hours at 55 degrees C.
