Many up‐to‐date equipements listed below are ready in use in the laboratory. Electron microscopies（TEM and SEM of Jeol）, a Ultramicrotome (Reichert）, a flow cytometer（FACScan）, a cell sorter（FACSsatar plus）, scanning electron microscopies （Bio rad MRC６００ and Ueiss LSM）, micromanipulation systems（Nikon‐Narishige and Zeiss‐Shimazu）, Bioimage analizers （Hamamatsu Pheotonics, Bio rad GS‐２５０ and Pharmacia Image Master）, a peptide synthesizer（Millipore ６００E）, a peptide sequencer（Shimazu PPSQ‐１０）,DNA sequancers （Perkin‐Elmer ３７３A‐７０ and Pharmacia AFL）, a DNA / RNA extraction system（Perkin‐Elmer ３４１‐３０），a real‐time surface plasmon detector（Fisons IAsys）, two P３ rooms, Super centrifugal machine （optima L‐９０K）. Many kinds of experiments for cell biology can be carried out with use of these equipements and others set in individual departments.
