Fig. 1From: Human S100A5 binds Ca2+ and Cu2+ independentlyMeasurements of Cu2+ binding to wildtype S100A5 in the presence of Ca2+ are difficult to interpret. Representative ITC trace showing Cu2+ titrated onto Ca2+-bound wildtype S100A5. Inset shows raw data trace. Data were characteristically noisy and the apparent fraction competent was systematically lowBack to article page
