Spectroscopic Studies for Rhodium (III) Binding to Apo-Transferrin

Figure 4

FT-IR spectra of free ApoHST and ApoHST-Rh (III) ion coordinates, at different time intervals (15, 30, and 60 min) at room temperature and physiological pH with higher metal concentrations (1 mM) and fixed ApoHST concentration (0.5 mM; 40 mg/mL) in 4000-1000 cm^-1 range.
