摘要:
Diagnosis system or immunoassay for the determination of the effective parathyroid hormone activity in a sample, and for a diagnosis and treatment of calcium metabolism disturbances, osteopathies and hyper- or hypoparathyroidisms. The parathyroid hormone activity is measured with the aid of an antibody which binds to an epitope in the region of the receptor binding structure 15 to 22 of the parathyroid hormone, and an antibody which recognises whether the amino-terminal end 1 to 3 of the parathyroid hormone is intact. The assay permits the antagonistic characteristics of some parathyroid hormone fragments to be taken into account.
摘要:
Method for determining the active parathyroid hormone content in a sample, wherein the component of parathyroid hormone polypeptide chains which are oxidized at one or more sites near the PTH receptor binding structure having the amino acids 15 to 22 are specifically excluded from the content determination. Oxidation of the parathyroid hormone occurs in particular in dialysis patients, their blood plasma being exposed to an oxidation stress in the dialysis. The invention is based on the use of antibodies which bind specific conformation epitopes of the oxidised or reduced parathyroid hormone and its fragments. Further, there is provided a test system for the quantitative determination of parathyroid hormone and active fragments hereof in a sample.
