Figure 6

Zeta potential measurements of BSA, Lys, and Mb systems. The concentration of BSA, Lys, or Mb was 1.5 × 10-5 mol/L. (A) Zeta potential of BSA vs. the concentration of DMSO; (B) Zeta potential of BSA vs. the concentration of Q. (A') Zeta potential of Lys vs. the concentration of DMSO; (B') Zeta potential of Lys vs. the concentration of Q. (A'') Zeta potential of Mb vs. the concentration of DMSO; (B'') Zeta potential of Mb vs. the concentration of Q. The concentration of DMSO was kept constant at 10% in B, B', and B''. Solid lines were used to illustrate the trends of the experimental data (in symbols) in both A, A', A'',B, B', and B''.
