Characterization of the DMAE-SS-PRX/β-gal complexes.
(A) Native agarose gel electrophoresis image of the DMAE-SS-PRX/β-gal complexes at various N/C ratios. (B) Mean diameter (closed circles) and zeta potential (open squares) variations of the DMAE-SS-PRX/β-gal complexes at various N/C ratios. Data are expressed as the means ± SD of triplicate experiments. (C) Relative enzymatic activity of the DMAE-SS-PRX/β-gal complexes at various N/C ratios. Data are expressed as the means ± SD of triplicate experiments. (D) Far-UV circular dichroism spectra of free β-gal (black line) and the DMAE-SS-PRX/β-gal complex (N/C 2) (blue line).
