Custom Monoclonal Antibody Development

At DIANA Biotechnologies, we develop custom rabbit recombinant monoclonal antibodies for demanding research, diagnostic, and early therapeutic discovery applications. Our workflow brings together three critical elements of successful antibody development: tailored immunogen preparation (including hapten synthesis), proprietary antigen-positive single plasma cell sorting, and proprietary DIANA-Ab high-throughput single-cell screening.


The resulting rabbit recombinant antibodies combine the strengths of rabbit immune responses with the consistency of recombinant production. Compared with conventional mouse hybridoma workflows or display-based discovery, they offer strong potential for high affinity, recognition of a wider range of targets (including small molecules), genetic stability, scalability, and reliable lot-to-lot consistency.


By identifying the best-performing clones directly from single plasma cells before cloning, DIANA-Ab helps reduce downstream uncertainty and focus resources on antibodies with the desired binding profile. The result is a streamlined path from immunogen design to recombinant monoclonal antibodies built for sensitive assays and challenging targets.

DIANA-Ab: Versatile and Scalable Discovery Platform

DIANA-Ab single cell discovery platform is suitable for diverse antibody discovery projects and technology integration

The DIANA-Ab platform extends high-throughput single-cell screening beyond standard antibody discovery. Its flexible workflow can be adapted to diverse discovery projects, from advanced binding-property screening and assay-ready antibody pair selection to integration with existing or future discovery campaigns. By combining single-cell resolution with adaptable screening design, DIANA-Ab helps identify well-characterized monoclonal antibody candidates for demanding therapeutic, research, and diagnostic applications.

Challenging Binding Modes


Screen for antibodies with advanced binding properties, including selectivity for holo versus apo protein forms, pH-dependent binding, or temperature-dependent binding behavior. This enables discovery of antibodies tailored to functional assays, conformational targets, and demanding application conditions.

Epitope Pairing for Sandwich Assays


Identify complementary antibody pairs that bind compatible epitopes on the same antigen and enable sandwich assay development, a preferred format for many diagnostic applications requiring high sensitivity, specificity, and assay robustness. DIANA-Ab HTS can provide a broad panel of complementary antibody pairs, giving you multiple options for sandwich assay development and optimization.

Compatible with Frozen Samples


Enable monoclonal antibody discovery from frozen splenocytes, bone marrow cells, and other relevant cell populations, including material generated as part of your polyclonal antibody campaigns. This allows valuable immune material to be preserved, revisited, and screened by DIANA-Ab HTS, reducing the need for repeating immunization campaigns.

Adaptable Across Species


Apply the DIANA-Ab workflow across antibody discovery projects using rabbits, rodents, humans, or camelids (VHH), enabling flexible integration with different antibody sources and discovery strategies.

CUSTOM ANTIBODY DEVELOPMENT

From Target Disclosure to Project Kick-Off

Every custom antibody project starts with understanding your target, application, and performance requirements. Our team evaluates the technical feasibility, proposes the most suitable development strategy, and defines a clear project plan before the work begins. Explore the steps below to see how we guide each project from first discussion to formal quote.

STEP 1: Target Disclosure

Tell us what your antibody needs to achieve

Share your target details, intended application, affinity and cross-reactivity requirements, and downstream assay needs. Based on this information, our team can assess feasibility and recommend the most suitable development strategy.

STEP 2: Project Strategy Presentation

A tailored development proposal for your target

Our experts prepare a project strategy tailored to your target and application. The proposal outlines the recommended immunogen design, screening approach, key development steps, estimated timeline, expected deliverables, and indicative pricing, giving you a clear view of how the project would be executed.

STEP 3: Technical Alignment and Q&A

Final technical alignment before project launch

Before moving forward, we align with your team technical details, project assumptions, success criteria, and practical requirements. This step ensures that the development strategy matches your expectations, and that open questions are addressed before the final quote.

STEP 4: Formal Quote

Clear scope and pricing for project launch

After technical alignment, we provide a formal milestone-based quote with defined scope, pricing, timelines, and deliverables for each development phase. Part of the project fee can be linked to predefined success criteria, such as target affinity, cross-reactivity profile, or performance in the customer’s application, helping share development risk while keeping the process transparent from the first step onward.

"DIANA Biotechnologies provided a professional custom monoclonal antibody development service. The communication was excellent throughout the project, timelines were met, and the delivered antibodies performed well. We were very satisfied with the collaboration.”
