A) Total glutathione in high and low toxin K. brevis homogenates (90–150 µg protein /ml) by DTNB reduction (0.2 mM) reduction after treatment of homogenate with GR. Samples were quantified against cysteine standards and normalized to protein concentration. (B) The ratio of GSH to total glutathione (GSx) was calculated based on the normalized results from Figs. 4 and 5A. High toxin (white bar) and low toxin (black bar) strains.
