a The ProtParam tool of the ExPASy proteomics server of the Swiss Institute of Bioinformatics (http://kr.expasy.org/tools/protparam.html) was used for the determination of the molecular weight (MW), theoretical pI, and hydropathicity based on the scale developed by Kyte and Doolittle (1982).
b Second virial coefficients (SVCs) was estimated by the following formula (Ho and Middelberg 2004)): SVC (mL mol/g2) = −0.0299 (MW) −5.233H, where MW is molecular weight of proteins in kDa and H is hydropathicity.
