Cellular insights for every
stage of early discovery
Our CETSA technology delivers direct evidence of protein behavior in their native environment, the cell, providing a clear link across the drug discovery pipeline.
One assay, endless possibilities
Turn complex biology into actionable insights across the entire discovery pipeline.
Unbiased Profiling Services
Observe how a compound influences proteins and pathways across the proteome without relying on predefined targets or assumptions.
Targeted Profiling Services
Validate mechanistic hypotheses and confirm that on-target engagement occurs in the intended cellular context.
Target
Discovery
Discover better drug targets, faster. See how proteins behave in real cells, and turn complex biology into clear, actionable insights.
Lead
Generation
Turn promising hits into proven leads. We help you see how compounds engage their targets in real cells – so you can focus on molecules that truly work.
Lead Optimization
We help you fine-tune your leads. We show what your compounds really do inside cells and reveal real-world target engagement and off-target effects, so you can push the best molecules forward with clarity.
Preclinical Studies
Move forward with confidence. Guide smarter preclinical decisions -helping you choose the right candidates to advance.
