Nucleic acid detection in cytoplasm

摘要

Detection probes labeled with fluorescent dyes, to which are bound nuclear membrane unpermeable molecules via linkers, having base sequences that can hybridize to a target nucleic acid. The probes are introduced into the cytoplasm of a living cell in which the target nucleic acid is present, and the target nucleic acid is detected by measurement of the change in fluorescence of the fluorescent dyes due to the formation of a hybrid of the target nucleic acid and the probes.
