SouthernBiotech offers a broad range of services for the development and production of monoclonal antibodies. Our Hybridoma
Development and Monoclonal Antibody Production Services include - immunization, cell fusion, cloning, characterization, and
production of your monoclonal antibody in vivo in BALB/c or immunocompromized (e.g., SCID, Nu/Nu, RAG-/-) mice, or in vitro in
flasks or bioreactors. Additional services include antibody purification and conjugation to fluorochromes and enzymes.
