Tissue-Clearing-CLARITY

US00000003_img01.png

CLALITY is the technique develped in the Deisseroth lab at Stanford University.
Chung, K. et al., Nature, 497, 332-337 (2013).
This protocol transforms intact tissues including whole organs into an optically transparent hydrogel-hybridized form, ready for molecular phenotyping and high resolution 3D imaging.
