Visualization of experimental glioma C6 by MRI with magnetic nanoparticles conjugated with monoclonal antibodies to vascular endothelial growth factor

We developed a method for obtaining iron oxide nanoparticles and their conjugation with monoclonal antibodies to vascular endothelial growth factor. The resultant vector nanoparticles were low-toxic and the antibodies retained their immunochemical activity after conjugation. The study was carried out on rats with intracranial glioma C6 on day 14 after its implantation. The intravenously injected nanoparticles visualized the brain tumor in contrast to nanoparticles conjugated with nonspecific immunoglobulins that did not accumulate in the tumor.
