Figure 2

Demetallation kinetics of Cu•HSA by EDTA in the absence and presence of His. Decrease of relative content of Cu-63 in HSA in time (a); effect of His on demetallatiuon of Cu•HSA by EDTA (b). Conditions: 10 μM Cu•HSA, 2–20 μM EDTA (a); 10 μM Cu•HSA, 10 μM EDTA, 0–100 μM His (b); incubation buffer 50 mM HEPES, 50 mM NaCl, pH 7.4; LC-ICP MS: column - 1 ml Sephadex G25 Superfine; elution buffer 200 mM NH4NO3, pH 7.4; flow rate 0.4 ml/min; injection volume 10 μl, Cu-63 was monitored by ICP MS. Figure was created and fittings were performed by program Origin 9 Pro (https://www.originlab.com/).
