Superimposed chromatograms of size calibration standards. Peaks from left to right represent blue dextran (MM 2 MDa), GSSG (MM 600 Da), GSH (MM 300 Da), and glycine (MM 75 Da). Stationary phase: Sephadex G-15 ( 3 1 × 1 . 0  cm I.D.); mobile phase: PBS-buffer (pH 7.4), flow rate: 1.0 mL/min; detector: ICP-AES at 193.091 nm; injection volume: 20 𝜇 L.
