Fully-human Monoclonal Antibodies Against Human EphrinB2 and EphB4 for Use in the Study of Cancer Pathogenesis

Posted Jun 06 2010 5:00pm

Description of Invention:
Ephrin receptor tyrosine kinases and their ephrin ligands have been implicated in cancer pathogenesis. Ephrin receptors and ligands affect tumor growth, invasiveness, angiogenesis, and metastasis. Ephrin signaling activities in cancer are complex and are only now beginning to be uncovered.

Researchers at the National Cancer Institute-Frederick, NIH, have developed a set of five fully-human monoclonal antibodies against human Ephrin-B2 and Ephrin type-B receptor 4 ("EphB4"). The antibodies were identified by screening a naïve human antibody phage display library against Ephrin-B2 and EphB4. These human monoclonal antibodies have high affinity and specificity for Ephrin-B2 and EphB4.

  • Research reagents for in vitro/in vivo investigation of Ephrin receptor and ligand interactions
  • Targeting reagents for in vivo imaging
  • Research reagents for protein co-crystallization

  • High affinity and antigen specificity
  • Bind both soluble ectodomains and cell surface-expressed molecules
