  • Title: High-performance liquid chromatography of uroporphyrinogen and coproporphyrinogen isomers with amperometric detection.
    Author: Lim CK, Li F, Peters TJ.
    Journal: Biochem J; 1986 Mar 15; 234(3):629-33. PubMed ID: 3718489.
    Abstract:
    A reversed-phase h.p.l.c. system, with an ODS-Hypersil column with acetonitrile or methanol in ammonium acetate buffer as mobile phase, is described for the separation of uro-and copro-porphyrinogen isomers. The porphyrinogens are detected amperometrically with sensitivity comparable with that of the fluorescent detection of porphyrins. The effects of pH, buffer concentration and organic modifiers on retention and resolution were studied. The method is suitable for both analytical and preparative separation of porphyrinogens.
