The SDS-PAGE analysis of separated BSA and LYZ by the Si-MNPs@SH. SDS-PAGE analysis of separated BSA (66 kDa) and LYZ (14.3 kDa) by the Si-MNPs@SH at pH 4.65 and pH 11, respectively. Initial protein (Control) and proteins desorbed from magnetic nanoparticles by 1 to 3 M NaCl and 0.1 M glycine solution (pH 2.3) were analyzed after protein incubation with Si-MNPs@SH for 10 min.
