The delivery of protein into living cells by use of membrane fusible erythrocyte ghosts.

摘要

We examined the effects of pretreatment of monkey kidney normal cells (CV-1) and human cervical tumor cells (HeLa) with membrane fusible erythrocyte ghosts (MFEG) encapsulating superoxide dismutase (SOD-MFEG) on adriamycin (ADM) cytotoxicity. The decrease in CV-1 cells with ADM was inhibited markedly, and the initiation of decrease in HeLa cells was delayed for 2 days by the pretreatment with SOD-MFEG, indicating that the delivered SOD held the activity in the cells.
