a Light emission from 2 × 104 lysed cells on different days after transfection with pMNTurboLuc or the minicircle vector encoding TurboLuc. Light emission of pMNTurboLuc is higher at day 7, while expression of the minicircle vector encoding TurboLuc (MINI-pMNTurboLuc) lasts for more than 14 days. b Representative images of sustained Luc expression in the liver of an animal after hydrodynamic injection of MINI-pMNTurboLuc
