AtomicLevel Cryo-EM

AtomicLevel Cryo-EM

Structure Tells You What Sequence Cannot

Knowing that an antibody binds is not enough. Knowing exactly where it binds, which residues drive affinity and selectivity, and how the antibody physically engages its target — that is the information that separates a good lead from a clinical candidate. FairJourney Bio's AtomicLevel Cryo-EM platform delivers that information, at atomic resolution, in under four weeks.

What AtomicLevel Cryo-EM Solves Across the Value Chain

Structural data is not a late-stage validation tool. At every stage of antibody discovery and development, the right structural question, answered at the right time, accelerates decisions and reduces risk. AtomicLevel Cryo-EM is built to answer those questions at the speed your programme demands.

Target Validation

What epitope do we need to target?

Structure Validation service: determine the 3D structure of your target protein to guide immunisation strategy and confirm the target is druggable at the intended site.

Hit Discovery

Fastest way to find an epitope-specific antibody?

Epitope-Based Hit Discovery service: a structure-first discovery workflow that uses cryo-EM to select epitope-specific, high-affinity antibodies directly from the NGS dataset of sorted B cells — delivering hits in under 12 weeks post terminal bleed.

Lead Selection

Which residues in the paratope make contact with the target?

Epitope Mapping service: atomic-level characterisation of the antibody-antigen interface, identifying the binding epitope, key interacting residues, and the molecular basis of affinity and selectivity.

Lead Improvement

How to improve the lead candidate?

Structure-based DeepDesign Engineering: structural output from Epitope Mapping feeds directly into DeepDesign Engineering, guiding targeted library design or in silico variant generation to achieve specific engineering objectives.

Development Candidate Selection

Which candidate has the best chance of becoming a product?

Structure Validation service: determine the 3D structure of your target protein to guide immunisation strategy and confirm the target is druggable at the intended site.

Service 3

Epitope-Based Hit Discovery

Structure-first discovery of epitope-specific, high-affinity antibodies

Conventional antibody discovery offers limited control over which epitope is targeted. Epitope-Based Hit Discovery uses cryo-EM to reverse this, identifying epitope-specific antibodies directly from the immune repertoire by structure, then recovering their sequences from the NGS dataset. The result is informed, accelerated discovery of antibodies with the epitope specificity required by the Target Product Profile.

Why this matters

Traditional discovery is time-intensive and offers limited control over epitope selection. AI-driven, sequence-from-structure workflows now enable a structure-first approach, delivering informed and accelerated discovery of desired antibodies by selecting for epitope specificity before a single expression experiment is committed.

Timeline

Under 12 weeks after terminal bleed.

Integration with DeepDesign Engineering

AtomicLevel Cryo-EM and DeepDesign Engineering are designed to operate as an integrated unit. Structural output from cryo-EM is not delivered as a report and filed — it is used immediately to design the next engineering iteration. The same scientific project lead manages both the structural work and the engineering campaign, ensuring that structural insight translates into experimental design without any translation loss or delay.

Cryo-EM structure determination (5 weeks) feeds into library-based engineering (12–14 weeks) or in silico approaches (5–6 weeks) — with the structural data reducing the experimental sequence space significantly and increasing the probability of identifying improved variants in every campaign.

Integration Across the Value Chain

AtomicLevel Cryo-EM connects forward and backward within the FairJourney Bio platform. Structural data from early-stage Epitope Mapping feeds into DeepDesign Engineering for lead improvement. Later-stage structure determination supports the development candidate decision and contributes to the regulatory package through FastTrack IND.

  • FullSpectrum Characterization — structural context for binding and selectivity data

  • DeepDesign Engineering — structure-guided library and in silico design

  • FastTrack IND — structural data for the regulatory submission package

What is Cryo-EM epitope mapping and why is it used in antibody development?

Cryo-EM epitope mapping determines the three-dimensional structure of an antibody-antigen complex at atomic resolution, identifying precisely which residues of the antigen are contacted by the antibody, and which residues of the paratope drive binding. This information answers questions that biochemical assays cannot: which epitope is being targeted, what is the molecular basis of affinity and selectivity, and how does the binding mode relate to the mechanism of action. This data directly guides rational and AI-based engineering, informing which positions to target in the next library or in silico design campaign.

What is epitope-based hit discovery and how is Cryo-EM used in antibody discovery?

Epitope-Based Hit Discovery is a structure-first antibody discovery service that uses Cryo-EM to identify epitope-specific antibodies directly from the immune repertoire. Following immunisation, antigen-specific B cells are sorted, and the antigen-pFab complex is imaged by Cryo-EM simultaneously with NGS of the sorted B cells. An AI-driven sequence-from-structure workflow then compares the structural output to the NGS dataset, identifying antibody sequences that bind the desired epitope. The result is informed discovery of high-affinity, epitope-specific antibodies in under 12 weeks post terminal bleed, with control over epitope selection that conventional discovery cannot match.

What resolution does FairJourney Bio achieve with Cryo-EM?

FairJourney Bio's AtomicLevel Cryo-EM platform delivers density maps at below 3.5 Å resolution as standard for the Epitope Mapping service. This resolution level enables the construction of validated atomic models with accurate side-chain placement, providing the residue-level interaction data needed to guide structure-based engineering. The 5th generation ThermoFisher Titan Krios™ microscopes at 300 kV provide the image quality required to achieve this consistently across diverse protein complexes.

This significantly reduces the experimental sequence space, focusing engineering efforts on the positions most likely to yield improvement, and increases the probability of identifying optimised variants in each campaign. The same scientific project lead manages both the structural work and the engineering campaign.
