Destabilizing the nuclear envelope resulted in significantly increased large-plasmid-transfection, indicating that nuclear localization may be more difficult for large plasmids While chloroquine may affect transfection by indirectly inhibiting lysosomal nucleases, this agent has a number of side effects beyond buffering lysosomes. Chloroquine (final concentration, 25 μ M) was added to the media 5 min before transfection. The effect of the compound was even more pronounced in transfections with linear forms of polyoma DNA, suggesting that chloroquine inhibits degradation of DNA absorbed by the cells. Nitric oxide (NO)1, an important signaling and cytotoxic molecule, is synthesized from L- arginine by isoforms of nitric oxide synthase (NOS) (1, 2). Either histone or chloroquine contributed to enhancing the levels of transfection activity of PLGE polymer. In general, the cells should be plated at a density so that they are 95-100% confluent at 24 hours post-transfection.
