Direct measurement of free coenzyme A in biological extracts by reversed-phase high-performance liquid chromatography.

O C Ingebretsen, M Farstad.   

Abstract

A high-performance liquid chromatographic system was developed with baseline separation of coenzyme A (CoASH) from dephospho-coenzyme A and acetyl-coenzyme A using isocratic elution. The chromatographic separation was achieved in a reversed-phase system with a high concentration (220 mM) of potassium phosphate buffer at pH 4.0 and appropriate amounts of methanol (ca. 12%). The eluate was monitored with a UV detector at 254 nm with the limit of detection at ca. 5 pmoles. The system could be used without modification for the estimation of the content of CoASH in biological extracts, e.g. mitochondria.
