Production of Secreted Antibody in Baculovirus Expression Vector System

Area of Science:

• Biotechnology
• Immunology
• Virology

Background:

• Monoclonal antibodies are crucial for disease treatment and antigen detection.
• Traditional mammalian cell expression systems face limitations in large-scale monoclonal antibody production.
• The Baculovirus Expression Vector System (BEVS) presents a viable alternative for producing these proteins.

Purpose of the Study:

• To demonstrate the production of a specific monoclonal antibody, b12, targeting HIV-1.
• To detail the methods for producing biologically active monoclonal antibodies using BEVS.
• To highlight BEVS as a scalable platform for antibody manufacturing.

Main Methods:

• Construction of transfer vectors for recombinant baculovirus generation.
• Generation of recombinant baculovirus carrying the antibody gene.
• Cultivation of insect cells for antibody production and subsequent detection.

Main Results:

• Successful production of the HIV-1 broadly neutralizing antibody b12 using BEVS.
• Demonstration of the feasibility of antibody production through the described BEVS processes.
• Characterization of the produced antibody's biological activity.

Conclusions:

• The Baculovirus Expression Vector System is effective for producing functional monoclonal antibodies.
• BEVS provides a scalable and efficient platform for meeting the growing demand for therapeutic antibodies.
• This approach facilitates the production of specific antibodies like the HIV-1 b12 antibody.
