Publication number: 20020155606Abstract: A target gene can be expressed site-specifically and with desired timing without damaging the cell itself or inducing mutation in a nucleic acid molecule within the cell. Expression of the above target gene is suppressed by allowing a caging agent represented by the following formula (1) to bind to a nucleic acid molecule containing the target gene; and the suppression of expression of the above target gene is cancelled by detaching the caging agent from the above nucleic acid molecule by UV-illumination.Type: ApplicationFiled: April 22, 2002Publication date: October 24, 2002Inventors: Hitoshi Okamoto, Hideki Ando, Toshiaki Furuta
