Abstract:

With the development of the microscopy and the big data acquisition processing system, the research direction gradually becomes the construction of biological structures by 3D imaging. However, because of opaque which leads to scattering of imaging light through the tissues, the depth of the imaging becomes a challenge. A technique named “clearing” can increase the organization transparency so that they can enhance the depth of the imaging and have a three-dimensional reconstruction. Being hydrophilic, the clearing reagents were divided into solvent-based clearing and aqueous-based clearing. The solvent-based clearing reduced water in the tissue and aqueous-based clearing used the hydration shell made by water to keep the fluorescent protein stability. In this article we introduced different clearing method and compared them from clearing time and retention in the fluorescence.
