Purified recombinant Human PTH protein Expression System: E.coli Bioactivity: The activity calculated by UMR106 cell/cAMP method corresponding to a specific activity of 0.9 x 10^4 Units/mg.
Parathyroid hormone (PTH), or parathormone, is secreted by the parathyroid glands as a polypeptide containing 84 amino acids. It acts to increase the concentration of calciumin the blood, whereas calcitonin (a hormone produced by the parafollicular cells of the thyroid gland) acts to decrease calcium concentration.
