Antibodies, also called immunoglobulins, serve as the body’s natural defense system, working by recognizing and neutralizing specific outside pathogens, such as viruses and toxins. Antibodies work in a highly specific manner, with different antibodies designed to recognize and neutralize highly specific antigens that may enter the body while minimizing harm to healthy tissues. In research, however, testing in humans can be both costly and complex, so many early research models rely on animal models to investigate antibody production, interactions with antigens, and efficacy, all within a controlled setting. Certain species of animals, like mice, rabbits, rats, and others, make up most animal models used in antibody research. Specifically, mouse and rabbit models are foundationally important to antibody work and research (Devasani, Guntuku, Sarabu, Muthyala, Palla, and Volety, 2025).
Mice and Rabbits in Antibody Research
Of all the species that are commonly used in antibody research, mice and rabbits are probably the top two species used. This is due to their capacity for antibody production. To be more exact, mouse models are foundational to produce monoclonal antibodies. Rabbit models, on the other hand, are used extensively in the production of polyclonal antibodies (Devasani et al., 2025).
Mouse models, specifically BALB/c models, are used extensively in the production of monoclonal antibodies. Monoclonal antibodies are typically produced using hybridoma technology, where antibody-producing B cells are fused with immortal myeloma cells. BALB/c mice are well known for having reproducible immune systems, something important for efficient hybridoma development. For studies particularly focused on immune regulation, C57BL/6 mice are commonly used. Mouse models are used because mice can easily be immunized with target antigens to reliably elicit immune responses, leading to the production of diverse antibodies in the mice which can be harnessed to further research applications (Devasani et al., 2025).
On the other hand, rabbit models are similarly used in the production of polyclonal antibodies. Rabbit antibodies offer several advantages, including higher affinity due to enhanced epitope recognition and a stronger immune response to small or poorly immunogenic antigens. They also demonstrate superior recognition of post-translational modifications and highly conserved proteins. Rabbits, specifically New Zealand White rabbits, are known for their robust immune responses and ability to generate a wide range of high affinity, antigen-specific antibodies. Rabbit models often exhibit higher affinity and specificity than what rodents can produce, making rabbit models valuable for a wide range of diagnostic and research applications (Devasani et al., 2025).
Humanized Mouse Models
Although mouse models are useful in producing antibodies for immunological research, they produce murine antibodies which can trigger an immune response when introduced to humans. To counter this, scientists have developed humanized mouse models for research use. These models are genetically engineered to carry components of human immunoglobulins in them, enabling them to produce fully human antibodies. They are valuable for reducing immunogenicity and enabling the development of therapeutic antibodies, particularly in oncology applications.

Antibodies are highly specific proteins designed to act as the natural defense system in the body against foreign antigens. Due to the cost and complexity of working with human models, animal models are frequently used in antibody studies and production. Because of their unique immune responses, rabbit and mouse models are of utmost importance in the production of antibodies.
