ABSTRACT:
Nucleic acid fragments labelled by radio isotape migrate at speeds that increase as the molecular weights decrease in a migration path served with a potential at both ends thereof. The migration path is constituted by a pipe-shaped gel support such as a glass tube. A ring-shaped scintillator is provided at a middle portion of the migration path to circumscribe the gel support, and whereby the beta rays are detected. A window may be formed in the glass tube at a portion opposed to the scintillator, so that the beta rays are not attenuated by the glass.
