Calcitonin (Dako Omnis)

Calcitonin is a 32 amino acid peptide hormone, produced in the parafollicular C cells of the thyroid. Calcitonin acts through its receptors, causing osteoclast-mediated bone resorption and calcium excretion by the kidney. The antibody is useful for the identification of calcitonin-producing C cells and is a useful aid for classification of medullary thyroid carcinoma.
