Plant’s Glowing Properties Produce Stunning Images of Microscopic Structures
October 3, 2021
- Microscopic staining has been used to enhance the visualization of samples at the microscopic level.
- Before viewing samples under a microscope, cells and tissues must be stained which requires long preparation processes.
- Another way to improve cellular visualization is by utilizing fluorescence tagging.
- A fluorescence tag is a molecule that attaches to detect proteins, antibodies, and amino acids.
- Many research studies utilize fluorescence microscopy to view plant internal structures.
- However, throughput can be hindered by using fluorescent antibodies or labels.
- Researchers proposed a minimal protocol that uses existing autofluorescence and aldehyde-induced fluorescence in plant structures to improve throughput in visualization.
- Researchers subjected twelve species to five fixative treatments.
- The following five fixative treatments are 1% paraformaldehyde and 2% glutaraldehyde, 2% paraformaldehyde, 2% glutaraldehyde, formalin-acid-alcohol, and 70% ethanol.
- Researchers used a confocal laser scanning system to collect images seen by a microscope.
- Researchers compared fixative influence on plant sample structural preservation and autofluorescence of tissues.
- Viridiplantae or green plant samples treated with formaldehyde produced useful structural data without requiring additional histological staining.
- Additionally, a microscope capable of fluorescence is the only equipment required for acquiring such images.
- The protocol allows for a high-throughput sample processing by obsoleting multiple-day preparations.
