Title:	Antibodies against ligand for receptor activator of NF-kB
Abstract:	Provided herein are antibodies that bind human RANKL polypeptides.
Inventor(s):	Anderson; Dirk M. (Seattle, WA)
Assignee:	Immunex Corporation (Seattle, WA)
Application Number:	09/865,363
Patent Claims:	1. A purified antibody that binds with higher affinity to a human RANKL polypeptide as shown in SEQ ID NO. 13 than to a murine RANKL polypeptide as shown in SEQ ID NO. 11. 2. An antibody according to claim 1 which is a monoclonal antibody. 3. A method of producing a monoclonal antibody according to claim 2, said method comprising culturing a cloned hybridoma cell that produces said antibody. 4. A method of producing a monoclonal antibody according to claim 2, said method comprising injecting into the peritoneal cavity of a rodent a cloned hybridoma cell that produces said antibody. 5. A cloned hybridoma cell that produces a monoclonal antibody according to claim 2. 6. A composition comprising an antibody according to claim 1. 7. A purified antibody that binds with higher affinity to a human RANKL polypeptide than to a murine RANKL polypeptide according to SEQ ID NO. 11, wherein said human RANKL polypeptide is selected from the group consisting of: a) a RANKL polypeptide comprising amino acids 69-313 of SEQ ID NO. 13; b) a RANKL polypeptide comprising amino acids 1-162 of SEQ ID NO. 13; c) a RANKL polypeptide comprising amino acids 162-313 of SEQ ID NO: 13; d) a RANKL polypeptide comprising amino acids 138-317 of SEQ ID NO:13; and e) a RANKL polypeptide comprising amino acids x to y of SEQ ID NO. 13, wherein x is an amino terminal amino acid between 69 and 162 of SEQ ID NO: 13, and y is a carboxy terminal amino acid between 313 and 317 of SEQ ID NO: 13. 8. An antibody according to claim 7 which is a monoclonal antibody. 9. An antibody according to claim 8, wherein the RANKL polypeptide comprises amino acids 69-313 of SEQ ID NO. 13. 10. An antibody according to claim 8, wherein the RANKL polypeptide comprises amino acids 1-162 of SEQ ID NO. 13. 11. An antibody according to claim 8, wherein the RANKL polypeptide comprises amino acids 162-313 of SEQ ID NO. 13. 12. An antibody according to claim 8, wherein the RANKL polypeptide comprises amino acids 138-317 of SEQ ID NO: 13. 13. A composition comprising an antibody according to claim 8. 14. A purified antibody that binds to a human RANKL polypeptide as shown in SEQ ID NO. 13, but that does not bind to a murine RANKL polypeptide as shown in SEQ ID NO. 11. 15. A purified antibody that binds with higher affinity to a human RANKL polypeptide as shown in SEQ ID NO. 13 than to a murine RANKL polypeptide as shown in SEQ ID NO: 11, wherein said antibody is generated by a method comprising immunizing with a RANKL polypeptide comprising amino acids x to y of SEQ ID NO: 13, wherein x is an amino terminal amino acid between 69 and 162 of SEQ ID NO: 13, and y is a carboxy terminal amino acid between 313 and 317 of SEQ ID NO: 13. 16. A method for generating an antibody, said method comprising immunizing with a RANKL polypeptide selected from the group consisting of: a) a polypeptide comprising amino acids 1-317 of SEQ ID NO. 13; b) a polypeptide comprising amino acids 69-313 of SEQ ID NO. 13; c) a polypeptide comprising amino acids 1-162 of SEQ ID NO. 13; d) a polypeptide comprising amino acids 162-313 of SEQ ID NO. 13; e) a polypeptide comprising amino acids 138-317 of SEQ ID NO. 13; and f) a polypeptide comprising amino acids x to y of SEQ ID NO. 13, wherein x is an amino terminal amino acid between 69 and 162 of SEQ ID NO. 13, and y is a carboxy terminal amino acid between 313 and 317 of SEQ ID NO. 13. 17. A method for preparing an antibody according to claim 16, wherein the antibody is elicited by immunizing with a RANKL polypeptide comprising amino acids 1-317 of SEQ ID NO. 13. 18. A method for preparing an antibody according to claim 16, wherein the antibody is elicited by immunizing with a RANKL polypeptide comprising amino acids 69-313 of SEQ ID NO. 13. 19. A method for preparing an antibody according to claim 16, wherein the antibody is elicited by immunizing with a RANKL polypeptide comprising amino acids 1-162 of SEQ ID NO. 13. 20. A method for preparing an antibody according to claim 16, wherein the antibody is elicited by immunizing with a RANKL polypeptide comprising amino acids 162-313 of SEQ ID NO. 13. 21. A method for preparing an antibody according to claim 16, wherein the antibody is elicited by immunizing with a RANKL polypeptide comprising amino acids 138-317 of SEQ ID NO. 13. 22. A method for preparing an antibody according to claim 16, wherein the antibody is elicited by immunizing with a RANKL polypeptide comprising amino acids x to y of SEQ ID NO. 13, wherein x is an amino terminal amino acid between 69 and 162 of SEQ 11) NO:13, and y is a carboxy terminal amino acid between 313 and 317 of SEQ ID NO. 13.
