Immunofluorescence Staining of Drosophila Brains for the Single-Cell Imaging of Glial Cells

Executive Industry Relevance

High-resolution immunofluorescence staining of Drosophila brains enables precise single-cell imaging of glial subpopulations, supporting mechanistic de-risking in early neurobiology discovery. This approach enhances predictive confidence in target validation by allowing direct visualization of cell-cell interactions and subpopulation-specific marker expression. The method is positioned to inform portfolio decisions where glial biology underpins disease-relevant pathways.
