Tip for a successful transfection—remove endotoxins!
Endotoxins are copurified during plasmid preparations from bacterial lysates and affect eukaryotic cell survival, ultimately leading to a lower transfection efficiency. Innovative mini-format technology reduces endotoxins in your plasmid prep, leads to more successful transfections, and simplifies your workflow.
