▎ 摘 要
NOVELTY - Method for confirming introduction of foreign genes into cells involves introducing a foreign gene into a target cell, processing a graphene oxide sensor in which a water-soluble polymer and a fluorescent conjugated probe are bound to the cell into which the foreign gene is introduced, and checking fluorescence emission in the cells, where the probe specifically binds to a substance produced in the target cell by the introduction of the foreign gene. USE - The method is useful for confirming introduction of foreign genes into cells. ADVANTAGE - The method simply and accurately confirms introduction of foreign genes and does not require an additional sampling process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for producing a foreign gene transduced cell, which involves introducing a foreign gene into a target cell, treating a graphene oxide sensor in which a water-soluble polymer is bonded to a carboxy group portion on the surface to a cell into which the foreign gene is introduced, and bounding fluorescent conjugated probe to the remaining portion of surface to which the water-soluble polymer is not bonded, confirming fluorescence emission in the cells, and culturing a cell whose light emission has been confirmed, where the probe specifically binds to a substance produced in the target cell by the introduction of the foreign gene.
