Effect of α-crystallin on DTT-induced aggregation of BSA.

<p>(A) The dependences of the light scattering intensity on time obtained at the following concentrations of α-crystallin: (1) 0, (2) 0.01, (3) 0.1 and (4) 1 mg/ml ([BSA] = 1.0 mg/ml; 2 mM DTT; 0.1 M phosphate buffer, pH 7.0; 45°C). <i>I</i> and <i>I</i>₀ are the current and initial values of the light scattering intensity, respectively. The inset shows the dependence of <i>I</i> on time obtained at the concentration of α-crystallin 0.5 mg/ml. (B) The dependence of d<i>I</i>/d<i>t</i> on time at α-crystallin concentration of 0.05 mg/ml. Points are the experimental data. The solid curve was calculated from Eq. (7).
