NOVEL HETERODIMERIC PROTEINS

摘要

The invention provides novel heterodimeric proteins including heterodimeric antibodies. The present invention describes novel immunoglobulin compositions that simultaneously co-engage antigens, where both of the antigens are bound monovalently. The novel immunoglobulins described preferably utilize heterodimeric Fe regions. Methods of using the novel immunoglobulin compositions, particularly for therapeutic purposes, are also described herein.
