SouthernBiotech offers a broad range of services for 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, immunocompromized (SCID, Nu/Nu, RAG-/-) mice, or in vitro in flasks or bioreactors. Additional services include antibody purification and conjugation to fluorophores, enzymes and D-biotin. Before initiating an antibody development project, the customer must provide SouthernBiotech with a signed assurance that any customer-supplied material/antigen is mycoplasma-free, non-infectious, non-carcinogenic, and has no known safety concerns to animals or humans.

Phase I: Immunization and Evaluation of Antibody Titer SBCS-30 I
Immunization of 3 BALB/c mice with your supplied and purified antigen. Includes Four (4) immunizations per our standard protocol and daily care. Test bleeds and ELISA data will be provided for your evaluation and decision to continue development.
Phase II: Fusion, Plating and Screening SBCS-30 II
Splenocytes of one of the mice are fused with a selected myeloma cell line. All specific antibody producing colonies are selected by ELISA for expansion. Supernatant from 5 of the best hybridomacontaing wells will be shipped to you for screening. Cryopreservation of up to Five (5) positive clones.
Phase III: Cloning, Expansion and Cryopreservation SBCS-30 III
Subcloning of one positive clone to monoclonality by two rounds of limiting dilution. ELISA screening to detect positive antibody-secreting subclones. Cryopreservation of Ten (10) vials of the hybridoma cell line and isotyping of one monoclonal antibody.
