A sensitive and selective method for the determination of total cysteamine in urine and plasma samples by gas chromatography (GC) has been developed. After reduction of the sample with sodium borohydride, the liberated cysteamine was converted into its N,S-diisobutoxycarbonyl derivative and measured by GC with flame photometric detection using a DB-210 capillary column. The calibration curve was linear in the range 0.2-5.0 nmol, and the detection limit, at a signal-to-noise ratio of 3, was ca. 0.5 pmol injected. Using this method, total cysteamine in urine and plasma samples could be accurately and precisely determined without any interference from coexisting substances. Analytical results for the determination of total cysteamine in urine and plasma samples from normal subjects are presented.

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D003543	Cysteamine	A mercaptoethylamine compound that is endogenously derived from the COENZYME A degradative pathway. The fact that cysteamine is readily transported into LYSOSOMES where it reacts with CYSTINE to form cysteine-cysteamine disulfide and CYSTEINE has led to its use in CYSTINE DEPLETING AGENTS for the treatment of CYSTINOSIS.
