Mouse Anti-Human Parathyroid Hormone

Mouse anti Human parathyroid hormone monoclonal antibody, clone BGN/1F8 recognizes human parathyroid hormone (PTH) also known as Parathyrin. PTH is a hormone produced by the parathyroid gland responsible for the regulation of calcium and phosphorus concentrations in extracellular fluid (Brown 1983).Human parathyroid hormone is produced in the parathyroid gland as a 115 amino acid single chain polypeptide, bearing a 25 amino acid signal peptide, a 6 amino acid pro-peptide sequence and an 84 amino acid mature hormone. (Keutmann et al. 1978).Defects in the PTH gene are a cause of familial isolated hypoparathyroidism (FIH), a condition characterized by hypocalcemia and hyperphosphatemia owing to levels of parathyroid hormone being insufficient to maintain extracellular calcium concentrations within normal parameters. Clinical features of FIH include cramps, seizures and tetany (Arnold et al. 1990). More rarely, hypoparathyroidism like disease, Pseudohypothyroidism (PHP1A) may be caused by mutations in the GNAS gene (Mantovani & Spada 2006) or defects in the PTHR1 gene (Cohen 2002) leading to Jansen metaphyseal chondrodysplasia (JMC), conditions where end organ resistance to PTH function exists .
