Custom antibody production services

We offer 5 discovery platforms: hybridoma, single B cell, polyclonal, phage display and de novo synthesis. Our extensive and unique phage display libraries such as the world’s first cancer library, allows us to take on any challenge. 

Your dedicated PhD expert evaluates your antigen, scientific objectives, application, timeline, and budget to recommend the most appropriate strategy. You receive a tailored plan designed to maximize success and performance in your specific assay.

Yes. We can generate antibodies from mouse, rat, rabbit, llama/camelid (VHH), and human donors, and more depending on your project’s goals and constraints.

Yes. We can work with any antigen type, including cells, peptides, proteins, small molecules, DNA constructs, VLPs, and nanodiscs. This allows us to successfully address membrane proteins, toxic antigens, highly conserved targets, and low-immunogenic molecules. We offer the strongest guarantees of the market, ensuring you get the solution for your project.

We offer peptide, DNA, protein, and cell-based immunization, as well as antigen presentation through VLPs and nanodiscs for complex membrane proteins.
Your dedicated PhD expert helps you select the most appropriate strategy based on your antigen type and the performance requirements of your application.

Yes. We can deliver hybridoma cell lines, recombinant antibodies, or both, depending on what best suits your workflow, scalability needs, or long-term production strategy. If needed we can also develop a custom stable cell line.

Yes. Full sequence information is delivered, and we offer reformatting into any desired format including VHH, Fab, scFv, bispecific formats, Fc fusions, and more.

Timelines vary depending on the technology, but thanks to our fast-track protocol we can generate your guaranteed custom antibody in less than 4 weeks.

Our workflows are fully flexible. You can start from an antigen, a target sequence, an existing antibody, a cell line… We adapt each step based on what you already have.

All custom antibody projects are fully IP-free. You retain complete ownership and exclusive rights to all sequences, antibodies, and cell lines. Confidentiality is protected through NDAs and strict internal procedures.

ProteoGenix has a strong track-record for projects involving highly complex or difficult targets. Thanks to our expertise, and extended panel of technology we can solve your toughest challenges.

Our service is fully tailored, IP-free, and built on a wide technology portfolio that covers all antigen types and applications. We can adapt to your timelines and offer a solution for any budget. You benefit from guaranteed performance in your chosen application, multiple Go/No-Go checkpoints, and direct guidance from a dedicated PhD expert.

For recombinant antibody production, our QC workflow systematically includes SDS-PAGE analysis under both reducing and non-reducing conditions.

For custom antibody development, we additionally validate each antibody in the client’s final intended application (e.g., ELISA, IF, WB, etc.), on top of SDS-PAGE (reducing / non-reducing) characterization.

Yes. We generate antibodies for therapeutic discovery, diagnostic development (ELISA, IHC, IF, WB, FC…), and all research applications. For each field, your project is secured by the strongest guarantees of the market.

Yes, our services work in synergy to guide you from antigen design to large-scale production. We can guide you through the entirety of your project. We offer humanization, affinity maturation, isotype switching, Fc engineering, sequence optimization, bispecific design, ADC development, and developability improvement and many more services…

We offer production from microgram-scale for screening to gram-scale manufacturing for preclinical programs.

We offer the strongest guarantees of the market. These guarantees are defined according to your project’s field. For example, in the case of a diagnostic development project, we guarantee your antibodies performance in your selected application. You can test them in your lab under your own conditions before paying the full price. 

Timelines, quality criteria, and deliverables are clearly defined before project initiation.

We offer a comprehensive range of antibody engineering services, including humanization, affinity maturation, bispecific formats, Fc-fusion, and other advanced constructs.

We can also re-express selected clones in various formats such as IgG, scFv, VHH and more..

If certain antibodies do not meet expectations, we can generate additional clones through secondary screening or subcloning to ensure the best possible outcome.

Custom antibodies are designed to target a specific antigen with high precision, unlike off-the-shelf antibodies, which are developed for broader use. They are the preferred choice when commercial antibodies lack the required specificity, sensitivity, or validation.
This is particularly important when working with novel or challenging targets, but also when an antibody exists for your target without being validated for your intended application(such as flow cytometry, IHC, or functional assays, etc.).
In short, when off-the-shelf antibodies are not truly “fit for purpose”, custom development ensures reliable, application-ready results.
