Cellular Target Engagement in Native Context
Directly quantitates ligand–target engagement inside intact cells, preserving native protein context and cellular environment.

Real-Time & Multi-Layered Data for Deep Analysis
Real-time & temperature-series measurements generate quantitative readouts, enabling layered comparison across compounds and targets.

Designed for Standard Lab Infrastructure
Compatible with standard real-time qPCR systems for fluorescence detection, requiring no specialized instrumentation.

MICRO-TAG® is based on a novel enzyme complementation chemistry that converts cellular target engagement into a measurable fluorescent signal.
The technology was developed and validated on 100+ drug targets, spanning hit discovery, hit validation and mechanistic analyses, before being standardized into reagent kits.

Time-resolved measurements that capture target engagement dynamics and mechanism.

DEL discovery of novel therapeutic candidates engaging with target under cellular conditions.

Time-resolved measurements of engagement with protein complexes with functional readout.

Specifically applicable to transcription factors, GPCRs, protein complexes, difficult enzymatic targets & other target classes.

Enabling DEL (DNA-Encoded Library) discovery under cellular conditions for de novo discovery of physiologically relevant target binders.

Applicable across conventional small-molecule modalities, active site & allosteric binders, glues, degraders, covalent inhibitors and peptides.
Access MICRO-TAG® reagents and workflows through our Success Program designed for rapid evaluation. The program allows you to run MICRO-TAG® assays directly in your lab + collaborate with CellarisBio team to design, execute and interpret MICRO-TAG® studies tailored to your discovery program.
