特徴

• Calcitonin (CT) is a peptide hormone produced by the parafollicular cells of the thyroid gland in mammals and by the ultimobranchial gland of birds and fish. Salmon calcitonin (sCT), which is more potent and longer lasting than human CT, has been used widely for the treatment of osteoporosis, paget's disease, hypercalcemic shock and chronic pain in terminal cancer patients. sCT is one of the many bioactive peptides that require C-terminal amidation for full biological activity.
• Calcitonin Acetate (Salmon) is a synthetic polypeptide of 32 amino acids in the same linear sequence that is found in clacitonin of salmon origin. MW: 432.
• Sequence:Cys-Ser-Asn-Leu-Ser-Thr-Cys-Val-Leu-Gly-Lys-Leu-Ser-Gln-Glu-Leu-His-Lys-Leu-Gln-Thr-Tyr-Pro-Arg-Thr-Asn-Thr-Gly-Ser-Gly-Thr-Pro-NH2
• Dimers and Aggregates:≤ 1% as determined by silver-stained SDS-PAGE gel analysis.
• Endotoxin:≤ 0.1ng/ug (IEU/ug) of Calcitonin.
• Protein Content:Protein quantitation was carried out by two independent methods:1. UV spectroscopy at 280nm. 2. Analysis by RP-HPLC.
• Reconstitution:Soluble in water and most aqueous buffers below and above the isoelectric point.
• Storage and Stability:Lyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile dH2O and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
