Abstract
The HPLC method presented here for the quantification of metal-binding thiols is considerably shorter than most previously published methods. It is a sensitive and highly reproducible method that separates monobromobimane tagged monothiols (cysteine, glutathione, γ-glutamylcysteine) along with polythiols (PC2, PC3, PC4 and PC5) within 23 min from a wide variety of samples. Total run time of the method is 35 min. Detection limits for thiols is 33 fmol for 10 μL injection. This method will be applicable to study the metal detoxification mechanisms for a wide variety of cell cultures and tissues of plants and trees including algae, Arabidopsis, crambe, rice, and red spruce.
