Protein Binding Characteristics of the Principal Green Tea Catechins: A QCM Study Comparing Crude Extract to Pure EGCG

Figure 4

Adsorption rates from EGCG and green tea solutions as a function of concentration. Each data point represents a complete experiment measurement on a clean and BSA-functionalized crystal. Data points are defined by the slope of mass vs. time curve at the beginning of the adsorption process (see Figure 2).
