ABSTRACT
Objective To develop a novel strategy for separation and purification of target protein by magnetic molecularly imprinted nanoparticles . Methods Fe3 O4 nanoparticles were synthesized through a hydrothermal method .A sol-gel technique was adopted to prepare imprinting layers .The adsorption capability of magnetic molecularly imprinted nanoparticles was investigated by kinetic , isothermal , and selective binding experiments .Results The imprinted nanomaterials could reach equilibrium within 30 min . The adsorption capacity was 44 .51 mg/g .The imprinting factor and selectivity coefficient were 3 .50 and 2 .92 ,respectively .The resulting imprinted polymers could selectively separate and enrich bovine hemoglobin from a bovine blood sample . Conclusion The prepared imprinted nanomaterials with good specific adsoprtion ability can provide an effective strategy for separation and purification of target protein .
ABSTRACT
Affinity chromatography (AC)is a type of liquid chromatography that makes use of biological-like interactions for separation and specific analysis of bioactive components. It has been widely used as a high-throughput screening method for the separation,screening and purification of the target molecules from complex samples with advantages such as high selectivity and high recovery efficiency.This article summarizes the biological effects of affinity chromatography, molecular imprinting chromatography, and dye ligands affinity chromatography.The review also encompasses the application of AC in the separation of chiral drugs,screening of active components,purification of target protein,and mechanism of the drug-protein interaction.Moreover,the prospects of its applications are also discussed.
