摘要
OBJECTIVE To observe enhancement of anti-tumor immunity by gene vaccine using nucleofection technology METHODS The technique of nucleofection was used to transfer effectively plasmid DNA into immature dendritic cells (iDCs); we studied immune responses regulated by DNA vaccine using real-time quantitative polymerase chain reaction (PCR) and western-blotting to optimize the follow-up lymphocyte activation. The anti-tumor capacity of lymphocytes primed by DCs was analyzed using lactate dehydrogenase with a non-radioactive cytotoxicity assay.
