Application
Calcitonin salmon can be used for calcitonin receptor/cAMP assay for assessing the presence of calcitonin receptors expressed by TRAP+ cells.The product can also be used as a test compound for studying as well as comparing the impact of calcitonin gene related peptide (CGRP) and salmon calcitonin (sCT) on gastric mucosal barrier in rats exposed to cold + restraint stress (CRS).
Biochem/physiol Actions
Calcitonin also refers as thyrocalcitonin is a 32 amino acid peptide hormone, which is present abundantly in seminal plasma compare to serum. It acts as a first messenger and hence regulate the the production of cAMP as well as mammalian sperm function. It may also facilitate the regulation of different isoforms of adenylyl cyclase. Additionally, salmon calcitonin stimulates the bone formation and inhibits the bone resorption in postmenopausal osteoporotic women.
Hypocalcemic hormone produced by the parafollicular C cells of the thyroid or by the ultimobranchial bodies of nonmammalian vertebrates. Decreases blood calcium and phosphate due to inhibition of resorption by osteoblasts and osteocytes.
Other Notes
32 amino acid polypeptide, 8 of which are conserved across all species.
Lyophilized from 0.1% TFA in H2O
Preparation Note
Calcitonin salmon dissolves in 1% acetic acid made in distilled water at a concentration of 1 mg/ml to yield a clear, colorless solution.
