(A) ITC titration profile of PFOA-HSA binding at pH 7.40. The temperature was 37°C and all the solutions contained 0.15 M NaCl. Each pulse corresponds to a 6.0-μl injection of 2.50 mM PFOA into the ITC cell (1.4685 ml) containing 0.010 mM HSA. (B) The area of each peak in A was integrated and corrected for the heat of dilution, which was estimated in a separate experiment by injecting the PFOA into the buffer.
