US Patent 8343737 Cell culture compositions capable of producing a VEGF-binding fusion polypeptide

The present invention provides cell culture compositions capable of producing fusion polypeptides that bind vascular endothelial growth factor (VEGF). The cell culture compositions of the invention comprise cells which contain an expression vector comprising a nucleic acid molecule encoding a fusion polypeptide that binds VEGF. The fusion polypeptides may comprise a VEGF receptor component having an immunoglobulin-like (Ig) domain 2 of a first VEGF receptor, an Ig domain 3 of a second VEGF receptor, and a multimerizing component.
