Product Description

Calcitonin salmon is a calcium-regulating hormone and a dual agonist of amylin and calcitonin receptors, which can stimulate bone formation and inhibit bone resorption.

Biological Activity I Assay Protocols (From Reference)

Targets	Amylin, Calcitonin receptor
ln Vivo	Fasting and non-fasted hyperglycemia are dose-dependently attenuated by oral calcitonin salmon treatment during the intervention period. Oral Calcitonin salmon treatment by dose reduces HbA1c levels by 1.7% and diabetic hyperglycemia by approximately 9 mM at the end of the study period. Moreover, oral Calcitonin salmon treatment results in a dose-dependently significant decrease in glucose excursions during the oral glucose tolerance test. Furthermore, oral Calcitonin Salmon treatment attenuates hyperglucagonaemia and hypersecretion of total glucagon-like peptide-1, primarily in the basal state, while maintaining hyperinsulinemia. Finally, at the conclusion of the study, pancreatic beta-cell function and beta-cell area are improved dose-dependently by oral Calcitonin salmon treatment[1].
Animal Protocol	Rats: Oral Calcitonin salmon (sCT: 0.5, 1.0, or 2 mg/kg) or oral vehicle is administered twice daily to male ZDF rats from 8 to 18 weeks of age. The control group consists of Zucker lean rats. The levels of pancreatic and incretin hormones, glycosylated hemoglobin (HbA1c), and blood glucose measured both fasting and non-fasting. Beta-cell area and function were assessed, and the oral and intraperitoneal glucose tolerance tests were compared[1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Molecular Weight*

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

Calculate the Mass of a compound required to prepare a solution of known volume and concentration
Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:

Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
Enter 25 into the Concentration (End) box and select the correct unit (mM)
Enter 25 into the Volume (End) box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
