Confident labeling, better data: AI guide support in affinity workflows

For almost two decades, NanoTemper has helped scientists cut through uncertainty, delivering high-quality, actionable data early so research can move forward with confidence.

That same commitment now extends to AI-driven labeling guidance in Dianthus and Monolith workflows. This article explores the philosophy behind the new tool, why structure matters in research, and what it means for the scientists using it. 

Affinity measurements are central to modern drug discovery and development. Across biologics and protein engineering, scientists depend on clear, early data to understand molecular interactions, guide decisions, and determine which candidates advance. As timelines compress, early choices in the affinity workflow increasingly shape data quality, interpretation, and confidence in downstream outcomes.

Navigating labeling choices with structure.

Choosing the appropriate labeling strategy requires careful consideration of various factors. Researchers regularly assess protein structure, residue accessibility, tag placement, and the needs of downstream assays. These choices highlight the complexity of protein biochemistry, yet they can also affect how quickly and confidently scientists can proceed.  

A structured labeling approach streamlines early workflow and builds quality affinity data, often inc

  • Starting with core protein attributes, such as tags, structural features, and accessible residues.
  • Considering batch labeling approaches, such as large-volume kits, to support consistency.  
Selecting fluorophores optimized for affinity measurements.
  • Matching labeling chemistry to protein characteristics
  • (e.g. NHS ester, maleimide,
  • tris-NTA). 
Validating protein concentration and degree of labeling (DOL) prior to assay execution

Taken together, these steps can help ensure that labeling improves data quality, reproducibility, and downstream confidence.

The AI Labeling Guide for Dianthus and Monolith systems

As AI becomes more prevalent in drug discovery, its value lies in bringing structure to complex decisions, surfacing relevant considerations quickly, and organizing information into a clear pathway that supports scientific expertise rather than replacing it.

NanoTemper offers a free AI Labeling Guide designed to support Dianthus and Monolith users in selecting the right labeling approach. The tool:     

  • Helps researchers identify alternative strategies worth considering. 

Uses available protein information, including UniProt and PDB, to suggest suitable labeling approaches. 

A non-active ingredient (e.g., sucrose, sorbitol) added to a formulation to stabilize the therapeutic molecule.

Excipient
  • Provides a structured starting point that can accelerate early decision-making.   

Labeling is a critical step in fluorescence-based affinity assays.

By introducing a fluorescent tag, it enables sensitive detection ]of binding events - the foundation of reliable interaction studies. When done carefully, it builds confidence in assay design and ultimately yields high-quality, accurate binding data. 

A range of well-established chemistries, including NHS ester, maleimide, and tris-NTA, offers the flexibility to tailor labeling strategies to specific protein characteristics and experimental needs.In this context, labeling isn't a barrier or complication; it's a trusted, reliable method. The key is selecting the approach that best fits the biology and assay specifics.
