Abstract
The invention provides a Vitaxin antibody and a LM609 grafted antibody exhibiting selective binding affinity to αvβ3. The Vitaxin antibody consists of at least one Vitaxin heavy chain polypeptide and at least one Vitaxin light chain polypeptide or functional fragments thereof. Also provided are the Vitaxin heavy and light chain polypeptides and functional fragments. The LM609 grafted antibody consists of at least one CDR grafted heavy chain polypeptide and at least one CDR grafted light chain polypeptide or functional fragment thereof. Nucleic acids encoding Vitaxin and LM609 grafted heavy and light chains as well as nucleic acids encoding the parental non-human antibody LM609 are additionally provided. Functional fragments of such encoding nucleic acids are similarly provided. The invention also provides a method of inhibiting a function of αvβ3. The method consists of contacting αvβ3 with Vitaxin or a LM609 grafted antibody or functional fragments thereof under conditions which allow binding to αvβ3. Finally, the invention provides for a method of treating an αvβ3-mediated disease. The method consists of administering an effective amount of Vitaxin or a LM609 grafted antibody or …
