Executive Industry Relevance

This method enables precise molecular mapping of axon-sorting molecules in the olfactory bulb, supporting target validation in neurodevelopmental research. By allowing quantitative comparison of protein expression patterns across glomeruli without section-to-section variability, it enhances predictive confidence in mechanistic studies of neural circuit formation. The approach provides a scalable, reproducible platform for de-risking hypotheses related to axon guidance and synaptic specificity in preclinical discovery pipelines.
