This work focused on scaling-down a monoclonal antibody SEC method, starting with a typical analytical-size SEC column (YMC-Pack Diol 5um, 300Å, 300x8.0mm) and ending with a small particle, shorter length, narrower-bore column (YMC-pack Diol 2um, 300Å, 150x4.6mm). The purpose of this experiment was to detail the differing performance characteristics exhibited by each column as physical properties were altered, one variable at a time.
