Calcium Homeostasis - PTH & Calcitonin

Calcium Homeostasis - PTH & Calcitonin

Calcium homeostasis is finely regulated by Parathyroid Hormone (PTH), Calcitonin and Vitamin D. Briefly, a decrease in calcium concentration in the blood triggers the release of PTH, an 84-amino acid hormone, from the parathyroid glands. An increase, however, causes the release of Calcitonin, a 32-amino acid protein from the thyroid parafollicular cells (C-cells).

AnaSpec carries a wide range of peptide solutions to support researchers working with Ca2+ metabolism.

For scientists in need of PTH or calcitonin peptide analogs containing unusual amino acids, AnaSpec carries a wide range of unusual amino acids that will facilitate your research. Contact us at for information about custom peptide synthesis.
