Seeking lipofection advice: I am trying to make cocoa butter into a cationic goop (ooops I mean reagent). To give an overall positive charge to liquid cocoa butter, my readings suggest adding Sodium, Calcium, possible iron filings and/or an electrical charge. What are your best suggestions for ionizing oils? Any other DIY lipofection protocol advice you want to give (i.e. how to mix in the DNA) would be very welcome. To you think creamed potato chips might be a readymade? Final lipofectant must be topical/noncaustic.
