摘要:
The present invention provides multivalent CD20-binding molecules, and compositions thereof, such as enriched compositions comprising large proportions of multivalent CD20-binding molecule relative to monovalent CD20-binding molecule. Certain multivalent CD20-binding molecules of the present invention comprise 1) two or more CD20 binding regions and 2) one or more Shiga toxin effector polypeptide regions derived from an A Subunit of a member of the Shiga toxin family. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for selective killing specific cell types and as therapeutics for the treatment of a variety of diseases, including cancers, tumors, and immune disorders. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for delivering agents into CD20-expressing cells, including for the intracellular labeling of CD20-expressing cells, collecting diagnostic information, and monitoring the treatment of variety diseases, such as cancers, tumors, and immune disorders which involve CD20-expressing cells.
