CUBIC protocol for whole-brain and whole-body imaging

CUBIC offers a fluorescent-preserving, high-performance and device-free tissue clearing method based on hydrophilic reagents. It enables reproducible whole-organ and whole-body clearing and rapid 3D imaging with LSFM. CUBIC also provides processing and analysis of 3D images for extracting biological information.
Therefore, CUBIC presents a platform of whole-organ/body imaging with single-cell resolution and image informatics, which enables a wide range of users to perform experiments targeting cellular and organ layers with multiple samples.

CUBIC clearing protocol with Reagent-1A
The CUBIC clearing protocol with Reagent-1A was developed for further fluorescent preservation, and was mentioned in our recent review: E. A. Susaki and H. R. Ueda (2016), Whole-body and whole-organ clearing and imaging techniques with single-cell resolution: Toward organism-level systems biology in mammals, Cell Chemical Biology.

Updated CUBIC-HistoVIsion (CUBIC-HV1.1) and representative data
We somewhat modified the original CUBIC-HistoVIsion (HV) 1.0 protocol reported in Susaki et al. (2020) to improve the signal-and-noise ratio. A set of z-stack images of the whole ICR mouse brain stained by CUBIC-HV1.1 with anti-NeuN, A555-conjugated antibody (Merck Millipore #MAB377A5) is provided below.

  • Gel embedding of CUBIC-R-cleared sample
    This movie explains how to embed the CUBIC-R-cleared sample in CUBIC-R/agarose, documented in Matsumoto et al. Nature Protocol (2019) and Susaki et al. Nature Communications (2020).
