Hello, don't really have a solution but I also deal with a similar issue when trying to transfect multiple plasmids. What method are you using for transfection? I use lipofection, but I've heard that electroporation may be more efficient.
Hey Ryan Yellamaty thanks for your response. I am using lipofection. While standardizing, I tried using lesser amount of plasmid for transfection since increasing the plasmid amount really did not work. Renilla got transfected only once when I decreased the amount of other plasmid. Haven't tried electroporation yet.
