Abstract

The present invention describes hetero-dimeric immunoglobulins or fragments thereof which bind to CD3 and a disease associated antigen. These hetero-dimeric immunoglobulins have been engineered to promote hetero-dimer formation during expression and can be purified to a high degree using a Protein A differential purification technique.
