Human plasma dynamically quenches the fluorescein at the initial point of oxygen radical absorption capacity (ORAC) assay

摘要

Dynamic fluorescence quenching of plasma of type 2 diabetic patients and healthy controls (Segment A—fluorescein solution in the absence of AAPH; Segment B—fluorescence decay curves of fluorescein in the absence of plasma; Segment C—fluorescence decay curves of fluorescein in the presence of human plasma; D—dynamic quenching of fluorescein solution by the plasma of both diabetic and healthy subjects at the initial point)
