WebBackground: A new parathyroid hormone (PTH) species, the N-terminal PTH form (N-PTH), is distinct from intact human PTH of 84 amino acid residues [hPTH(1-84)] and is recognized in a 3rd-generation assay of "whole" PTH (wPTH; the 1-2 epitope) but not in a 2nd-generation assay of "total" PTH (tPTH; the 12-18 epitope). N-PTH usually … WebSecreted PTH undergoes cleavage and metabolism to form carboxyl-terminal fragments (PTH-C), amino-terminal fragments (PTH-N), and mid-molecule fragments (PTH-M). Only those portions of the molecule that carry the amino terminus (ie, the whole molecule and PTH-N) are biologically active. The active forms have half-lives of approximately 5 minutes.
Webterminal fragment (1–34) of PTH, and a second antibody reacts with the C-terminal fragment (39–84) of PTH. In the first step of the assay, the PTH molecules are captured on magnetic nanoparticles coated with anti-N-terminal PTH antibodies (Fig. 2a). Since the combined surface area of the magnetic particles is large, this capture phase goes very WebThe normal half-life of intact PTH is 5 minutes, C-terminal fragment 30-40 minutes, and N-terminal fragment 5 minutes. In renal failure the half-lives may extend to as much as 30 minutes for the intact molecule, 24-36 hours for the C-terminal fragment, and 30 minutes for the N-terminal fragment.
WebOne antibody is prepared to bind only the mid-region and C-terminal PTH 39-84 and this antibody is biotinylated. The other antibody is prepared to bind only the N-terminal PTH 1-34 and this antibody is labeled with horseradish peroxidase [HRP] for detection. Although mid-region and C-terminal fragments are bound by the biotinylated anti- WebThe Roche cobas assay for determining intact parathyroid hormone (PTH) employs a sandwich test principle in which a biotinylated monoclonal antibody reacts with the N-terminal fragment (1-37) and a monoclonal antibody labeled with a ruthenium complex reacts with the C-terminal fragment (38-84).
