Results within hours for small subsets to 2 weeks for >5k antibodies.

A critical step in antibody selection.

Epitope binning is crucial in the early stages of antibody discovery, as it facilitates the categorization of antibodies with similar target binding regions on the target. In general, insights in the epitope landscape of antibody panels significantly advance development of multi-targeting approaches. Additionally, understanding which protein regions are targeted by your antibody panel can significantly enhance intellectual property security.

Maximize early triaging with high efficiency

High precision with multi-dimensional clustering

LENSai proprietary Epitope Binning algorithm includes:

  • Antibody sequential and structural profiling
  • Docking information, accounting for steric hindrance and glycosylation sites
  • Atomic interactions of Ab-Ag complexes
Multiple output formats providing actionable insights:

3D Grid view:

Clusters group antibodies that share a similar target binding region. Quick view on cluster proximity.

Graph view:

Lines show similarity between Abs within and between clusters (red=high, blue = low). Select and zoom in (panel on right). Ab closest to all other members of its cluster are denoted with black border.
