제목 Immobilization of cystein-tagged Protein G on amine modificated silica coated magnetic nanoparticles
초록 This work reported the immobilization of cystein-tagged Protein G onto amino modifiedmagnetic nanoparticles(MNPs) for control and enhancement ofantibody orientation and immobilization. Portein G wasobtained from genetic engineeredStreptococcus aureus as an activated site for antibody and magnetic nanoparticles were used the 30nm of silica-coated iron oxides. The overal process involved the conjugation of amino-functionality of MNPsand thiol group of cross-linkerin N-terminal ofprotein G. The conjugation efficiency was calculated over 40%. The synethetic routes was confirmed by the detailed characterization such as ATR FT-IR,andDRIFT UV-Vis.
