Objective To explore the expression of Green Fluorescent Protein Gene transduced into the rats via Sofast reagent (Sofast) and Lipofectamine2000 (Lipo) so as to select the better vector and feasible gene transfer route to submandibular lymph nodes(SMLN).

• 目的探讨阳离子聚合物Sofast基因转染试剂(Sofast)和阳离子脂质体Lipofectamine2000(Lipo)经不同途径向大鼠转入绿色荧光蛋白基因(PEGFP-N2),观察其在颌下淋巴结(SMLN)的表达。
