Figure 4: The time course of HSA damage photosensitized by DDP (V) TPP with or without NaN3. The sample solution containing 10 μM DDP (V) TPP and 10 μM HSA in a 10 mM sodium phosphate buffer (pH 7.6) was irradiated for the indicated period. The concentration of damaged HSA was estimated from the fluorescence intensity of HSA using equation (1).
