Comparison between different methods to prepare Ni-MNPs for protein binding and purification. Three synthesis procedures in the literature were compared based on the steps that are required to synthesize (a) Ni-NTA MNPs40 (b) glutardialdehyde MNPs (immobilization for non-his-tagged enzymes)49 and (c) NiFe2O4 MNPs used in the current study. No washing or separation step was included.
