Fig. 6From: Humanized bispecific antibody (mPEG × HER2) rapidly confers PEGylated nanoparticles tumor specificity for multimodality imaging in breast cancerIn vivo MR imaging of αHER2/SPIO and αDNS/SPIO. Nude mice bearing MCF7/HER2 (right m.f.p) and MCF7/neo1 (left m.f.p) tumors were intravenously injected with αHER2/SPIO and αDNS/SPIO (10 mg/kg). a Mice were sequentially imaged at pre-treatment and 24 h with a MR imaging scanner. b The result was calculated as the percentage of negative signal enhancement by [pretreated signal intensity (SI0)-treated signal intensity (SI24)]/SI0 * 100Back to article page
