  • Title: Separation and quantification of monothiols and phytochelatins from a wide variety of cell cultures and tissues of trees and other plants using high performance liquid chromatography.
    Author: Minocha R, Thangavel P, Dhankher OP, Long S.
    Journal: J Chromatogr A; 2008 Oct 17; 1207(1-2):72-83. PubMed ID: 18760414.
    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, gamma-glutamylcysteine) along with polythiols (PC(2), PC(3), PC(4) and PC(5)) within 23min from a wide variety of samples. Total run time of the method is 35min. Detection limits for thiols is 33fmol for 10microlL 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.
