    Area of Science:

    • Materials Science
    • Microscopy Techniques
    • Biological Sciences

    Background:

    • Epoxy resins are widely used for embedding biological tissues for high-resolution microscopy.
    • Sectioning embedded tissues into continuous ribbons is crucial for serial reconstruction.
    • Conventional sectioning methods can be challenging, leading to ribbon fragmentation.

    Purpose of the Study:

    • To present a simple yet effective method for producing strong, heat-resistant epoxy resin ribbons.
    • To facilitate the process of serial sectioning for three-dimensional reconstruction.

    Main Methods:

    • Painting contact cement onto the leading and trailing faces of the epoxy block before sectioning.
    • Floating the forming ribbon onto a water drop stabilized by a wax line.
    • Directing the ribbon into a stainless steel trough for transfer and expansion on a hot plate.

    Main Results:

    • The contact cement treatment results in the formation of strong, heat-resistant ribbons.
    • The water flotation and trough method allows for continuous ribbon collection.
    • Serial ribbons are easily obtained and mounted onto slides for further analysis.

    Conclusions:

    • This technique significantly improves the ease and quality of serial sectioning of epoxy-embedded samples.
    • The method facilitates detailed three-dimensional reconstruction of fine tissue structures.
    • It offers a practical advancement for researchers in microscopy and histology.
