Executive Industry Relevance

Dynamic measurement of glycosomal pH in living Trypanosoma brucei enables precise interrogation of metabolic regulation under nutrient stress, directly informing target validation for parasite-specific pathways. The integration of a ratiometric biosensor with flow cytometry provides quantitative, high-throughput readouts essential for early discovery and mechanistic de-risking. This capability supports portfolio decisions by clarifying metabolic vulnerabilities and enabling robust screening of modulators affecting parasite viability.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct measurement of metabolic pathway responses to environmental changes in live parasites.
• Supports functional validation of glycolytic enzymes as drug targets by linking pH dynamics to enzyme activity.
• Facilitates mechanistic de-risking by quantifying organelle-specific responses to nutrient deprivation.
• Provides predictive confidence for prioritizing metabolic targets in anti-parasitic drug discovery.

Screening & Assay Development

• Delivers a validated, inducible biosensor system for reproducible pH measurement in high-throughput formats.
• Standardizes quantitative readouts using flow cytometry, improving assay scalability and reproducibility.
