以阴道滴虫单克隆抗体为模型，使用Ｎ－羟基琥珀酰亚胺棕榈酸酯（ＮＨＳＰ）为偶联剂将棕榈酰基与单抗共价键结合，并经此烃链将单抗插于脂质体双分子膜上。用间接荧光抗体试验和细胞作用检验表面结合单抗的脂质体对阴道滴虫有特异性结合。实验结果证明，用单抗修饰脂质体在体外寻靶作用是有效的。 Monoclonal antibodies against Trichomonas vaginalis were used as a model, and N-hydroxysuccinimide palmitate (NHSP) was used as a coupling agent to covalently bond the palmitoyl groups to the mAb. The monoclonal antibody was inserted into the lipid Plastid bilayer membrane. The indirect fluorescent antibody test and the cell effect of the surface-bound mAb liposomes showed specific binding to Trichomonas vaginalis. The experimental results show that the use of monoclonal antibody modified liposomes in vitro targeting is effective.
