Comparison Table
Catalent
enterprise_vendorCDMO providing antibody discovery, development, and manufacturing services for biologics.
Assay-driven candidate selection workflows designed to produce decision-ready panels for downstream development teams.
Catalent’s antibody discovery delivery is built around controlled generation and screening of antibody panels, with multiple discovery routes available based on target and desired antibody format. Project teams can expect a workflow that moves from initial screening through affinity and specificity refinement using measurement outputs tied to decision gates. Documentation and study outputs are geared toward internal triage so selection teams can compare hits using consistent assay readouts.
A key tradeoff is that deep integration depends on how tightly internal stakeholders define success criteria up front for specificity, developability, and cross-reactivity boundaries. Catalent fits best when a program needs managed discovery throughput and consistent sample handling across multiple candidate iterations, rather than ad hoc exploratory screening.
- +Structured hit triage to narrow candidates using measurement-driven decisions
- +Managed sample handling across iterative screening cycles and candidate refinement
- +Good handoff materials that support internal selection and downstream planning
- +Assay breadth for specificity and developability risk screening

How to Choose the Right Antibody Discovery
We see the biggest separation in how each option handles epitope-to-constraint evidence across the workflow, especially in specificity profiling and cross-reactivity assessment. The best fits make it easy to trace how your inputs turn into ranked antibody discovery outputs with clear auditability.
Evidence traceability across discovery steps
Why it matters
Evidence traceability across discovery steps matters because antibody discovery decisions often get revisited when results conflict. If you can’t follow which data led to a rank, you waste time re-running or second-guessing runs.
How to check
Ask the demo team to show one antibody record from raw import to final output and click through every linked result. Look for step-by-step provenance fields (who/when and input-to-output links) rather than only a final report.
Specificity profiling workflow support
Why it matters
Specificity profiling support matters because antibody discovery users need consistent readouts that let them compare candidates across assays. Without a clear workflow, your team ends up reconciling results manually in spreadsheets.
How to check
During the demo, load a small panel of assay outputs and watch how the tool normalizes and displays specificity outcomes. Confirm it supports importing the same candidate across multiple assay runs and keeps the comparisons tied to each run.
Cross-reactivity assessment handling
Why it matters
Cross-reactivity assessment handling matters because antibody discovery failures frequently hide in off-target behavior. Good handling keeps those findings attached to each candidate so you can filter or revisit decisions later.
How to check
Request an example where the same candidate appears with both target-binding and off-target signals. Check whether the output distinguishes sources of cross-reactivity (assay type or sample context) and supports filtering by those markers.
Epitope binning mapping and visualization
Why it matters
Epitope binning mapping matters because antibody discovery teams use it to avoid redundant candidates and to plan combinations. If the visualization doesn’t match the evidence, you can’t confidently group antibodies.
How to check
Ask to import a binning dataset and show how bins are created and displayed. Verify you can open a bin to see which candidates and which inputs produced it, and confirm the view works with multiple experiments.
Automation and API surface for batch runs
Why it matters
Automation and API surface matters because antibody discovery data arrives in batches and gets re-run during iteration. When the API and automation are missing or shallow, updates stay stuck in manual workflows.
How to check
Ask whether the tool supports scripted import/export and whether it can generate the same output structure across multiple runs. Look for documented endpoints or job configuration that let a lab run the workflow repeatedly without UI-only steps.
RBAC, audit log, and run governance
Why it matters
Run governance matters for antibody discovery because teams often share candidates and revisit results months later. Without RBAC and audit trails, changes in ranked outputs become hard to justify and reproduce.
How to check
In the demo, have them describe role permissions for who can edit candidates vs. who can view. Then ask to show an audit trail for a change (what changed, when, and from which run), and confirm whether older outputs remain accessible.
Red flags
- Outputs show rankings but not the evidence links behind them
- Specificity and cross-reactivity data end up flattened into spreadsheets
- Epitope binning visuals don’t trace back to the underlying inputs
Fit by situation
- If your team repeatedly revisits candidate decisions after new assay reads, prioritize Evidence traceability across discovery steps.
- If you run candidate panels and need consistent comparisons across assays, prioritize Specificity profiling workflow support.
- If you coordinate candidate grouping for combinations, prioritize Epitope binning mapping and visualization.
