Electropherogram of analytes from EO sampling of OHSCs. EO sampling from an OHSC with only ggACSF in the Petri dish (a), or with 99.22 nM of cysteamine (b), 65.81 μM of Cysteine (c), 574.8 nM of homocysteine (d) added in ggACSF. Cysteamine (CSH), homocysteine (Hcy), cysteine (Cys) and glycylglycine (Gly-Gly) peaks marked on the plot are all ThioGlo-1 derivatized peaks. Separation conditions are described in experimental section.
