WebJun 24, 2013 · Intact PTH is biologically active and clears very rapidly from the circulation with a half-life of less than four minutes 1. PTH undergoes proteolysis in the parathyroid glands, but mostly peripherally, particularly in the liver but also in the kidneys and bone, to give N-terminal fragments and longer lived C-terminal and mid-region fragments. WebPTHrP is cleaved into N-terminal (1-86) and C-terminal (109-141) peptides, and various attempts have been made to develop assays that target the N-terminal or C-terminal PTHrP peptide. The Nichols Institute of Diagnostics in 1993 first described a sandwich immunoradiometric assay for PTHrP, with a reference range of <0.7 – 2.6 pmol/L.
