I would like to perform functional studies in primary human keratinocytes and I am looking for an expression system that offers high transfection effiency. In principle, an adenovirus-transduced gene expression system might be a good choice, but the main disadvantage is the requirement of a laboratory with biosafety level 2. Yesterday, I stumbled over baculovirus-transduced gene expression, and interestingly, there is no need for BL2. Is there anyone familar with this expression system? Thank you very much in advance
