Specific and nonspecific adsorption of proteins onto the pretreated materials. The ratios of adsorbed proteins to the loaded cellulose (Cellic Ctec2) and dry mass (BSA) for SF_STEX (black bars), SF_{STEX+HEX150/8} (dark grey bars), and SF_{STEX+HEX190/4} (light grey bars) are shown. The protein loadings were equivalent to 10 FPU/g cellulose (panel a) and 20 FPU/g cellulose (panel b). The data represent the mean values of 4 experiments. Error bars indicate the standard deviation
