発明の名称 (英語) Method for rendering tissue transparent, reagent for rendering tissue transparent, and tissue observation method NEW
発明の概要(英語) (CN104956201)
A method for rendering tissue transparent, said method including a step in which tissue is immersed in a water-soluble solvent including 2,2'-thiodiethanol, and glycerol and/or a non-ionic organic iodine compound, is provided as a technique with which, using a simple operation, and without using toxic or hazardous organic solvents, various organs can be rendered sufficiently transparent without inducing changes therein.
In this method for rendering tissue transparent, it is preferable that a mixed solvent of 2,2'-thiodiethanol, glycerol, and a non-ionic organic iodine-compound aqueous solution be used for the water-soluble solvent.
