MICRO-TAG® technology supports a wide range of discovery applications where understanding target engagement in a cellular context is critical. Teams can engage with MICRO-TAG® using standardized reagent kits, collaborative scientific solutions, or a combination of both to achieve their goals.

DNA-encoded library campaigns generate large numbers of candidate binders, but validating on-target engagement in cells remains a key challenge. MICRO-TAG® enables cellular validation of DEL hits to support confident prioritization.
Questions Addressed:
• Do DEL hits engage the target in cells?
• Which hits should be prioritized for synthesis?
• Are apparent binders biologically relevant?

Early hit lists often contain compounds that perform well in biochemical assays but fail to engage the target in cells. MICRO-TAG® enables direct measurement of cellular target engagement, helping teams distinguish true cellular hits from false positives.
Questions Addressed:
• Does this compound engage the target in cells?
• How does engagement compare across a series?
• Are observed phenotypes likely on-target?

Functional consequences of target engagement are often difficult to resolve using traditional assays. MICRO-TAG® provides a cellular approach to directly link compound binding with downstream biological effects.
Functional Responses :
• Signaling pathway activation
• Ternary complex formation
• Protein–protein interactions
Applicable across conventional small-molecule modalities, particularly active site binders, allosteric inhibitors, molecular glues, degraders, covalent inhibitors and peptides.
MICRO-TAG® reagents are compatible with a growing catalog of more than 100 validated targets spanning multiple protein classes.
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.
