Compositions and methods for detecting cyclic analogs of hPTH

摘要

The present invention is directed to novel antigens, antibodies and antigen binding fragments thereof, and to immunoassays and kits using these antigens and antibodies. The compositions and methods are useful in the determination of levels of cyclic analogs of hPTH in sample fluids, such as serum or plasma. The antibodies and methods of the invention have the particular advantage of possessing binding specificity for cyclic analogs of hPTH.
