The VGTI Monoclonal Core offers monoclonal and polyclonal antibody production (DNA immunization) in mice and purification of antibody produced from existing cell lines (a stand-alone phase IV).  A monoclonal project is typically done in four stages.

Stage One Immunization
4 mice are given 2-3 injections with protein antigen. Antisera titers are determined to identify animals for fusion.
Stage Two Fusion and hybridoma screening
Spleen cells from 2 mice are fused with mouse myeloma cells to generate hybridomas.  After ELISA screening, hybridoma supernates are delivered to the client for testing.
Stage Three Cloning and characterization of hybridomas
Parent hybridomas are limit dilution cloned, providing for stable growth and antibody production and monoclonality.
Stage Four Antibody production and purification
In vitro scaleup in bioreactors provides antibody in the 75-100 mg range. 
Antibodies are purified to greater than 90% using two chromatography steps.
