Composições compreendendo multímeros otimizados de her1 e her3 e métodos para usos dos mesmos

摘要

The invention provides for compositions comprising engineered Her3 multimers with improved binding affinity. Such multimers include, but are not limited to, Her1/Her 3 heterodimers in which the Her3 ligand binding domain has been optimized to increase binding to Her3. The composition also can include mixtures of Her 1 homodimers, Her 3 homodimers, and Her 1/Her 3 heterodimers.
