Second Harmonic Generation Imaging in a Rat Model to Study Tubulin Defects

Executive Industry Relevance

Second harmonic generation (SHG) imaging enables label-free, quantitative detection of microtubule abnormalities in disease-relevant brain tissue, supporting mechanistic de-risking in neurodegeneration research. This approach provides predictive confidence for target validation and early discovery by directly visualizing tubulin defects and associated myelin disruption. Integrating SHG imaging into discovery pipelines enhances the ability to triage targets and prioritize assets with translational potential.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct visualization of microtubule defects for functional target validation.
• Supports mechanistic de-risking by linking tubulin abnormalities to myelin disruption.
• Provides quantitative imaging outputs to inform predictive confidence in target selection.

Screening & Assay Development
