What types of specimens can be embedded using this method?
The method is suitable for small model organisms such as zebrafish, Drosophila, and Daphnia.
How long can the embedded samples be stored?
Samples can be stored for long periods, allowing for multiple imaging sessions over the years.
What is the main advantage of using acrylic resin for embedding?
Acrylic resin provides rigid immobilization and preserves the anatomical features of the specimens.
What precautions should be taken during sample preparation?
Care should be taken to avoid sample damage and to prevent air bubbles during the embedding process.
Can this method be used for human tissue diagnostics?
The technique has potential applications in human tissue diagnostics, although it is primarily demonstrated with model organisms.
What imaging techniques can be used after embedding?
Following embedding, methods such as histology or electron microscopy can be employed for further analysis.
