High-affinity, blocking antibodies — guaranteed

 

Cut straight to human antibodies

In therapeutic development, fully human antibodies offer the greatest potential for regulatory approval by the FDA or EMEA. They help minimize immunogenicity and adverse reactions in patients. With four distinct human antibody generation platforms (phage display, single B cell screening, hybridoma development, de novo antibody generation), we guarantee fully human antibodies for virtually any antigen.
 

Strategy you can trust, experts you can count on

Having the right platforms is important—but what makes the real difference is pairing them with top scientific minds. At ProteoGenix, your project is handled by PhD-level experts or seasoned professionals with years of antibody development experience. Their goal: design the most effective strategy from day one—so you can move forward faster and more confidently.
 

Time is everything — save months

Our proprietary phage display platforms, together with the largest panel of high-diversity human antibody libraries—naïve or immune—allow us to deliver high-affinity sequences in just 1 month.
 

Hit the target with picomolar affinity (in the 10-12M range)

High-affinity antibodies are essential for optimizing therapeutic efficacy and minimizing side effects. At ProteoGenix, we generate these powerful blocking antibodies through:

  • Phage display with our exclusive human libraries (naïve, immune, autoimmune, cancer, COVID-19)
  • Single B cell sorting from humanized mice

 

Risk-free discovery with our “No Win – No Fee” guarantee

If we don’t deliver binders, you pay nothing for the service—simple as that. It’s more than a promise; it’s our commitment to your success.

Tackling your toughest antibody challenges — with strategy and precision

At ProteoGenix, we harness the synergy of AI-driven discovery, expert wet-lab execution, and one of the most diverse antibody generation platforms on the market. This unique approach allows us to address even your most complex R&D challenges with complete confidence.
We’ve already supported clients on demanding scientific projects such as:

  • Generating antibodies against membrane proteins (e.g., GPCRs, peptide-MHC complexes)
  • Developing antibodies targeting highly conserved antigens (e.g., cytokines, interleukins)
  • Isolating antibodies against low-expression or cryptic antigens (e.g., tumor neoantigens)
  • Addressing rapidly mutating targets (e.g., COVID-19 variants)
  • Targeting hard-to-reach compartments (e.g., CNS antigens)

These are just some of the scientifically challenging projects where we delivered high-quality monoclonal antibodies. We also support clients with operational constraints, such as:

  • Tight turnaround times
  • Limited project budgets
  • Toxic or weakly immunogenic targets
  • Animal-free antibody generation
  • Optimized developability for downstream success

For each case, our experts craft tailor-made strategies to align perfectly with your scientific goals and technical requirements.

What our clients say

We have been working together with ProteoGenix since 2020. Using phage display, they helped our team to develop several antibodies with effective blocking effects. We are pleased with their services and look forward to continue working together with them as we advance our research and bring the biologics to the clinical stage.

I requested ProteoGenix’s services for the generation of neutralizing anti-COVID-19 antibodies by Phage-Display. They designed an optimised strategy for this purpose which led to great results, with 4 antibodies identified as cross-reactive and neutralizing against all the current variants of concerns. During the whole project, Proteogenix strived to ensure the best quality of their final deliverables, especially by including additional screenings against emerging variants as the pandemics evolved. Their proactivity was key to obtain promising and relevant blocking antibodies in only a few months. I highly recommend them for both their level of expertise and the personalised service they offer.

We are developing a novel immunotherapy and needed a highly potent monoclonal antibody. Currently the development of a novel antibody requires lengthy and expensive humanization process. We thus decided to screen for binders via phage display screening instead using a human library. Proteogenix proposed just that. We provided our purified target antigen and in only one month several high affinity binders were obtained. We were able to quickly clone and produce a monoclonal antibody from the sequences provided. What should have taken 6 to 8 months was done in 2 for a fraction of the cost and for an equivalent quality.

I requested ProteoGenix’s services for the generation of antibodies against a malarial protein by phage display. Their naive human library, which is comprised of 368 donors, is a unique resource which was one of the criteria I used to select their company. They optimized their standard screening strategy to be able to identify two specific clones, that they then expressed with very high yields in their proprietary XtenCHOTM cell line. I highly appreciated their level of expertise and their commitment to go beyond expectations, and I would recommend them for their reactivity and the high quality of their services.
