The results obtained using 7AAD staining are much clearer than those obtained using PI. Using flowcytrometry stained and unstained, transfected and non-transfected populations can be separated much more easily.

The amount depends on the cell type and on the DNA construct. As a rule of thumb 400 ng of DNA per well should be applied. However, for some cells or constructs even 100 ng may be sufficient.

Insect cells are cultivated at lower temperatures than E.coli or mammalian cells (S2 cells at 24°C, Sf9 cells at 28°C).Therefore they need a dedicated incubator with appropriate temperature.
