Construction of Rabbit Immune Antibody Libraries

Area of Science:

• Immunology
• Biotechnology
• Molecular Biology

Background:

• Rabbits offer advantages over mice for generating target-specific antibodies due to higher affinity and stronger immune responses.
• Current monoclonal antibody production predominantly uses murine hybridoma technology, limiting access to rabbit-derived antibodies.
• Phage-display technology presents an alternative for generating monoclonal antibodies from non-murine species.

Purpose of the Study:

• To describe the construction of a rabbit immune Fab library.
• To facilitate the isolation of high-affinity, target-specific rabbit monoclonal antibodies.
• To overcome limitations of traditional hybridoma technology for rabbit antibody generation.

Main Methods:

• Construction of a rabbit immune Fab library from immunized rabbit B cells.
• Amplification of antibody variable domain repertoires and assembly into a Fab repertoire via PCR.
• Cloning of Fab genes into a phagemid vector, transformation into E. coli, and rescue of a phage-displayed library.

Main Results:

• Successful construction of a functional rabbit immune Fab library.
• The library enables rapid screening and identification of target-specific rabbit monoclonal antibodies.
• Demonstrates the feasibility of using phage display for rabbit antibody discovery.

Conclusions:

• Phage-display selection of rabbit immune Fab libraries is an effective strategy for obtaining high-affinity monoclonal antibodies.
• This method provides a valuable alternative to hybridoma technology for rabbit antibody generation.
• Facilitates the development of novel rabbit monoclonal antibodies for research and therapeutic applications.
