Analysis of total urinary catecholamines by liquid chromatography: methodology, routine experience and clinical interpretations of results [PDF]
, 1983 A simple routine method is described for simultaneous assay of total urinary adrenaline, noradrenaline and dopamine. The catecholamines are pre-purified on a small ion-exchange column, separated by reversed phase ion-pair liquid chromatography, and are ...

Identification of novel components of Trypanosoma brucei editosomes [PDF]
, 2003 The editosome is a multiprotein complex that catalyzes the insertion and deletion of uridylates that occurs during RNA editing in trypanosomatids. We report the identification of nine novel editosome proteins in Trypanosoma brucei.
