Take a Revolutionary Approach to Deep Image



Data provided by Dr. Hiroshi Hama, Tetsushi Hoshida and Dr. Atsushi Miyawaki, Laboratory for Cell Function Dynamics, Brain Science Institute, RIKEN Biotechnological Optics Research Team, Center for Advanced Photonics, RIKEN Cooperation with Olympus

The original recipe reported by the Miyawaki team in 2011 termed Scale was an aqueous solution based on urea that is limited because the transparency process itself can damage the structures under study.
The research team spent 5 years improving the effectiveness of the original recipe to overcome this critical challenge, and the result is ScaleS, (we called SCALEVIEW-S) a new technique with many practical applications. SCALEVIEW-S creates transparent brains with minimal tissue damage, that can handle both florescent and immunohistochemical labeling techniques, and is even effective in older animals.
The new technique creates transparent brain samples that can be stored in SCALEVIEW-S solution for more than a year without damage. Internal structures maintain their original shape and brains are firm enough to permit the micron-thick slicing necessary for more detailed analyses.


  • Easy-to-use
  • No special equipment required
