Monoclonal Antibodies

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.

Available Services for Hybridoma Development	Cat. No.
Pre-Immunization Antigen Processing and Modification
Homogenization of Antigen in Gels or Nitrocellulose Slices	SBCS-19
Conjugation to KLH for Immunization	SBCS-22K
Conjugation to BSA for Screening	SBCS-22B
Dialysis into Physiological Buffer	SBCS-22D
Phase I - Immunization and Evaluation of Antibody Titer	SBCS-30I
Immunization of Three (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-30II
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 Five (5) of the best hybridoma-containing wells will be shipped to you for screening. Cryopreservation of up to Five (5) positive clones.
Phase III - Cloning, Expansion, and Cryopreservation	SBCS-30III
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.
Phase IV - Amplification	SBCS-30IV
Production and shipment of monoclonal antibody supernatant from one selected clone
