While murine systems dominated early antibody development, rabbit-derived monoclonal antibodies have emerged as a superior alternative for targets requiring high-affinity recognition of complex or conserved epitopes. Rabbits exhibit distinct immunological advantages, including expanded CDR3 diversity, enhanced somatic hypermutation, and the capacity to generate antibodies against small molecules and post-translational modifications—capabilities often unattainable in rodent models.
Phage display technology, a gold standard for in vitro antibody discovery, is uniquely suited to exploit these biological advantages. By decoupling antibody selection from in vivo immunization constraints, this platform enables systematic mining of rabbit antibody repertoires, overcoming limitations of traditional hybridoma methods such as low fusion efficiency and epitope bias. Creative Biolabs leverages this synergy to deliver a Rabbit Monoclonal Antibody Discovery Service, integrating phage display with proprietary library engineering and AI-driven optimization. Our service accelerates the generation of high-affinity, functionally validated mAbs for applications ranging from oncology therapeutics to neurodegenerative disease biomarker discovery.
Our workflow is engineered for precision, efficiency, and scalability across five integrated phases:

In this case study, we highlighted a successful collaboration with a client in the field of biological research, where we provided a comprehensive service for advanced rabbit antibody discovery using phage display technology.
|
Antigen Preparation The client provided information and materials for a small molecule hapten. Based on the data provided and project objectives, we prepared the antigen material for both immunization and subsequent screening. |
Rabbit Immunization
We immunized three rabbits and continuously monitored their immune titers. After several rounds of testing, we selected the two rabbits with the most robust immune responses for further use in library construction. |
|
Immune Rabbit Fab Library Construction
Library Capacity >109
Library Accuracy > 95%
High Library Diversity
Using peripheral blood mononuclear cells (PBMCs) and spleen cells from the two selected rabbits, we constructed a phage display Fab library. The library met all quality control standards, ensuring a high diversity of antibody candidates for the screening process. |
|
Rabbit Fab Library Screening
We performed 4 rounds of screening using conjugated small-molecule antigens. Effective enrichment of binders was observed, confirming the presence of high-affinity antibodies specific to the target antigen. The screening process was optimized to identify the most promising candidates.
|
Binder Validation
Phage-based assays were used to validate the binders. We sequenced all positive clones and identified approximately 5 unique antibody candidates. These sequences were delivered to the client, providing them with a selection of high-potential antibodies for further development. |
