(a) Decrease in the concentration of des[58–110] at
pH 8.0, 15°C under three solution conditions: in the presence of
DTTred alone (260 μM) (○), in the presence of
DTTox and DTTred (100 mM and 260 μM,
respectively) (□), and in the absence of any redox reagent
(●). (b) Decrease in the
concentration of des[26–84] at pH 8.0, 15°C under three solution
conditions: in the presence of DTTred (260 μM)
(○), in the presence of DTTox and
DTTred (100 mM and 260 μM, respectively) (□),
and in the absence of any redox reagent (●).
