CAR-based Functional Screening

Bridging discovery to functional activity

Overview
Functional Screening

Beyond Binding-Based Selection

Binding is a critical starting point in antibody discovery, but it does not always predict how a candidate will perform in a biological system. Whereas traditional approaches focus on identifying binders or measuring secretion, these signals do not always correlate with downstream activity, making the right approach less straightforward as factors such as target biology, mechanism of action, and project timelines all come into play.

Nona’s functional screening platform is designed to address this gap by evaluating candidates directly in a cellular system, enabling selection based on biological activity rather than binding alone.

Functional Screening Across Therapeutic Applications

Functional Screening Platform

Nona’s functional screening platform evaluates antibody candidates in a cellular system, enabling selection based on biological activity rather than binding alone. By placing candidates in a context where signaling and downstream responses can be observed directly, this approach provides a more relevant view of how antibodies perform.

The NonaCarFx™ platform streamlines CAR binder discovery through a proprietary system that integrates fully human VH domains, derived from HCAb libraries, directly into CAR-formatted lentiviral vectors. This functional screening approach evaluates candidates through target-specific stimulation in a cellular context, enabling selection based on measurable biological activity rather than binding alone.

By enabling discovery and validation within a single workflow, NonaCarFx™ allows researchers to identify high-performing therapeutic candidates more efficiently, with iterative rounds of stimulation and sorting supporting enrichment of functional leads, while maintaining applicability across both ex vivo and in vivo systems.

Overview of NonaCarFx™:
  • Direct Library Cloning: HCAb libraries are seamlessly cloned into CAR-lentiviral vectors.
  • Reporter Cell-Based Validation: Dual-readout tools identify functional CAR binders based on activation and GFP expression.

   

  • Comprehensive Output:
    Delivers candidates with high sequence diversity and stable CAR expression.
  • Multi-Round Screening:
    Sequential target-specific stimulation refines lead selection for precise functionality.
  • It will shorten the workflow for positive plasma cell screening from months to a single day.

  • The high throughput screening with 14K or 20K chips dramatically decreases labor costs for screening more than 10,000 cells.

  • Direct screening with individual plasma cells prevents the diversity loss/bias during hybridoma screening.
