1. An isolated human monoclonal antibody comprising human heavy chain and human light chain variable regions comprising the amino acid sequences shown in SEQ ID NO: 7 and SEQ ID NO: 8, respectively.
2. The antibody of claim 1 which completely inhibits M21 cell adhesion to vitronectin.
3. The antibody of claim 1 , comprising a human IgG heavy chain and a human kappa light chain.
4. The antibody of claim 1 , comprising an IgG1 or IgG3 heavy chain.
5. A pharmaceutical composition comprising the antibody of claim 1 and a pharmaceutically acceptable carrier.
6. A composition according to claim 5 wherein the antibody is combined with an anti-neoplastic agent selected from the group consisting of a radiopharmaceutical, an estrogen receptor modulator, a retinoid, a topoisomererase inhibitor, a cytotoxin, an alkylating agent, a nitrogen mustard, a nitrosourea , an antimetabolite, a mitotic inhibitor, and a radiosensitizer.
7. A composition according to claim 6 wherein the alkylating agent is dacarbazine.
8. An immunoconjugate comprising the antibody according to claim 1 linked to a therapeutic agent.
9. The immunoconjugate of claim 8 wherein the therapeutic agent is a cytotoxin.
10. The immunoconjugate of claim 9 wherein the therapeutic agent is a radioisotope.
11. A pharmaceutical composition comprising the immunoconjugate of claim 8 and a pharmaceutically acceptable carrier.
12. An article of manufacture for human pharmaceutical or diagnostic use, comprising packaging material and a container comprising a solution or a lyophilized form of isolated human anti-alpha-V subunit antibody according to claim 1 .
13. The article of manufacture of claim 12 , wherein said container is a component of a parenteral, subcutaneous, intramuscular, intravenous, intrarticular, intrabronchial, intraabdominal, intracapsular, intracartilaginous, intracavitary, intracelial, intracelebellar, intracerebroventricular, intracolic, intracervical, intragastric, intrahepatic, intramyocardial, intraosteal, intrapelvic, intrapericardiac, intraperitoneal, intrapleural, intraprostatic, intrapulmonary, intrarectal, intrarenal, intraretinal, intraspinal, intrasynovial, intrathoracic, intrauterine, intravesical, bolus, vaginal, rectal, buccal, sublingual, intranasal, or transdermal delivery device or system.
14. An isolated human monoclonal antibody according to claim 1 produced by a method comprising transfecting a host cell or transgenic animal or transgenic plant or plant cell capable of expressing in recoverable amounts said antibody with a nucleic acid molecule encoding said antibody and recovering the antibody from cell, animal or plant.
15. An isolated human monoclonal antibody according to claim 1 , wherein said antibody binds purified human α v β 3 and α v β 5 integrins with an affinity of at least one selected from at least 10 −9 M, at least 10 −10 M, at least 10 −11 M, or at least 10 −12 M.
