PDI-sAb sensitivity to reducing reagents. To determine the sensitivity of synthesized PDI-sAb to reducing reagents, various concentrations of DTT (A) or GSH (B) were added to PDI-sAb (○ 5 μM, ■ 50 μM, □ 500 μM, ◆ 5 mM, ● 30 mM). Fluorescence increased immediately after the addition of reducing reagents and reached peak value within the first 30 seconds. Fold increase in RFU at 300 sec (C) reveals a difference in potency of the reducing reagents. (*, p < 0.05; **, p < 0.01, ***, p < 0.005)
