Investigation of monoclonal antibody dimers in a final formulated drug by separation techniques coupled to native mass spectrometry.

abstract：:Therapeutic antibodies continue to develop as an emerging drug class, with a need for preclinical tools to better predict in vivo characteristics. Transgenic mice expressing human neonatal Fc receptor (hFcRn) have potential as a preclinical pharmacokinetic (PK) model to project human PK of monoclonal antibodies (mAbs)...
