Plant genetic engineering led to the production of plant-derived mAb (mAbP), which provides a safe and economically feasible alternative to the current animal expression systems. In this study, the expression level of mAbP SO57 between with and without Lys-Asp-Glu-Leu (KDEL) was compared in transgenic plant. PCR and PT-PCR analyse showed stable gene insertion transcription of heavy and light chain genes of mAbP SO57 with or without KDEL in plant, respectively. We validated expression of mAbP SO57 by western blot. Western blot showed the significantly higher expression level of mAbP SO57 with KDEL compared to without KDEL. Flow cytometry (FACS) analysis showed that the Fc domains of both purified mAbP and mammalian-derived mAb (mAbM) evidenced similar binding activity to the FcγRI receptor (CD64). High performance liquid chromatography (HPLC) analysed, glycosylation patterns of mAbP SO57 with or without KDEL. The mAbP SO57 with KDEL had glycan profile with both oligomannose type (47.6%) and golgi type (52.4%), while the mAbP SO57 without KDEL had only golgi type (100%) glycans. Neutralizing analysis with rabies virus CVS-11 showed the similar neutralizing activity between mAbP SO57 with and without KDEL. These results suggest the potential of mAbP SO57 for rabies immunotherapy, regardless of plant specific glycan structures.
