Executive Industry Relevance

Quantifying endogenous ER-mitochondria interactions is critical for de-risking early discovery hypotheses related to cellular signaling and metabolic regulation. The in situ proximity ligation assay enables sensitive, multiplexed detection of organelle contact sites without protein overexpression, supporting predictive confidence in disease-relevant systems. This capability strengthens portfolio decisions at the intersection of target validation and mechanistic pathway analysis.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct visualization and quantification of ER-mitochondria contacts at the molecular level.
• Supports mechanistic de-risking by confirming endogenous protein proximity in fixed cells and tissue biopsies.
• Facilitates functional target validation for pathways involving calcium signaling and organelle crosstalk.
• Improves predictive confidence for advancing targets implicated in metabolic and signaling disorders.

Screening & Assay Development

• Provides a standardized, reproducible assay for quantifying protein-protein interactions at sub-organelle resolution.
• Enables multi-condition testing to assess the impact of compounds or genetic perturbations on ER-mitochondria contacts.
