1. An antibody or binding fragment thereof which specifically binds to the tail portion of the Vascular endothelial growth factor (VEGF) receptor HSFLT PEA-1 P10 of SEQ ID NO:533, wherein the tail portion consisting of the amino acid sequence ELYTSTSPSSSSSSPLSSSSSSSSSSSS corresponding to amino acids 706-733 of SEQ ID NO:533.
2. A kit comprising the antibody of claim 1 and at least one reagent for performing an immunoassay.
3. The kit of claim 2 , wherein said immunoassay is selected from the group consisting of an enzyme linked immunosorbent assay (ELISA), an immunoprecipitation assay, an immunofluorescence analysis, FACS analysis, an enzyme immunoassay (EIA), a radioimmunoassay (RIA), and a Western blot analysis.
4. A method of detecting the binding of the antibody of claim 1 to an epitope of a polypeptide comprising the amino acid sequence ELYTSTSPSSSSSSPLSSSSSSSSSSSS, wherein the epitope corresponds to amino acids 706-733 of SEQ ID NO:533, the method comprising the steps of contacting the antibody to a sample from a patient and detecting the binding of said antibody to said polypeptide.
5. The method of claim 4 , wherein the patient is suspected of having a disease selected from the group consisting of peripheral vascular disease, ulcers, diabetes, ischemia, and cancer.
