Compositions and methods for the diagnosis and treatment of tumor
The present invention is directed to compositions of matter useful for the diagnosis and treatment of tumor in mammals and to methods of using those compositions of matter for the same.
1. An isolated antibody which binds to a polypeptide consisting of:
(a) the amino acid sequence shown as SEQ ID NO:7;
(b) the amino acid sequence shown as SEQ ID NO:7, lacking its associated signal peptide;
(c) an amino acid sequence encoded by the full-length coding sequence of the nucleotide sequence shown as SEQ ID NO:3; or
(d) an amino acid sequence encoded by the full-length coding sequence of the cDNA deposited under ATCC accession number 230651.
2. The antibody of claim 1 which is a monoclonal antibody.
3. An antigen-binding fragment of the antibody of claim 1 .
4. The antibody of claim 1 which is a chimeric or a humanized antibody.
5. The antibody of claim 1 which is conjugated to a growth inhibitory agent.
6. The antibody of claim 1 which is produced in bacteria.
7. The antibody of claim 1 which is produced in CHO cells.
8. The antibody of claim 1 which induces death of a cell to which it binds.
9. The antibody of claim 1 which is detectably labeled.
10. The antibody of claim 1 which is conjugated to a cytotoxic agent.
11. The antibody of claim 10 , wherein the cytotoxic agent is selected from the group consisting of toxins, antibiotics, radioactive isotopes and nucleolytic enzymes.
12. The antibody of claim 10 , wherein the toxin is selected from the group consisting of maytansinoid and calicheamicin.
13. The antibody of claim 10 , wherein the cytotoxic agent is a toxin.
14. The antibody of claim 13 , wherein the toxin is a maytansinoid.
