Liposomes, loaded with gadolinium (Gd) ions using different membrane-incorporated chelating lipids and functionalized with monoclonal anti-CD138 (syndecan-1) antibody were prepared. Nuclear Magnetic Resonance Dispersion (NMRD) analysis showed that use of the polychelating amphiphilic polymer (PAP) increases both the Gd content and the spin–lattice relaxivity of the Gd-loaded-PAP–liposomes as compared to Gd–DTPA–BSA equivalents. The potential application of contrast syndecan-1– and Rituximab–liposomes, for application as a novel minimally invasive diagnostic agent for multiple myeloma and non Hodgkin's lymphoma was investigated.
制备了脂质体,其中装载了使用不同膜结合螯合脂质和单克隆抗CD138(syndecan-1)抗体功能化的钆(Gd)离子。核磁共振分散(NMRD)分析表明,与Gd-DTPA-BSA等效物相比,使用多螯合两性聚合物(PAP)可增加Gd含量和Gd-PAP-脂质体的自旋-晶格弛豫率。对比syndecan-1和利妥昔单抗脂质体的潜在应用,作为多发性骨髓瘤和非霍奇金淋巴瘤的新型微创诊断剂进行了研究。
