简介：
Overview
This article presents a whole-mount immunohistochemical approach to visualize neurofilament protein expression in the extrahepatic biliary tract of Suncus murinus. The method allows for the analysis of nerve distribution in visceral organs, particularly those that are small or irregular.
Key Study Components
Area of Science
- Neuroscience
- Immunohistochemistry
- Visceral organ analysis
Background
- Whole-mount immunohistochemistry is a technique used to visualize nerve distribution.
- Suncus murinus serves as a model organism for studying visceral organ innervation.
- This method is advantageous for small or irregular organs that are challenging to assess with standard techniques.

What is whole-mount immunohistochemistry?
Whole-mount immunohistochemistry is a technique used to visualize specific proteins in tissues, allowing for the analysis of structures such as nerve distributions.
Why use Suncus murinus as a model organism?
Suncus murinus is a suitable model for studying visceral organ innervation due to its small size and the complexity of its organ systems.
What are the advantages of this method?
The method is straightforward, does not require complicated procedures, and has a high success rate for visualizing nerve distributions.
Can this technique be applied to other species?
Yes, the whole-mount immunohistochemistry method can be adapted for use in various species, particularly for analyzing small or irregular organs.
What are the key steps in the procedure?
Key steps include flushing the animal with PBS and paraformaldehyde, followed by the immunohistochemistry staining process.
Who demonstrated the procedure in the article?
The procedure was demonstrated by Yidan Dai, a graduate student, and Shuang-Qin Yi, a research fellow from the laboratory.
