DLS measurement results for the particle size distribution of the tested solutions of <i>α</i>-chymotrypsinogen A(II).

<p>All proteins are dissolved in 25 mM pH 7.0 HEPES-Na at 295K. A): Two peaks appeared, showing that the solution was not monodisperse; B): Only one peak appeared, showing that the solution was monodisperse, and its corresponding SLS measurement result was considered reliable and the data could be included for subsequent analysis.
