Etelcalcetide hydrochloride
Based on 2 publication(s) in Google Scholar
Etelcalcetide hydrochloride (AMG 416 hydrochloride; KAI-4169 hydrochloride) is a synthetic calcimimetic as an activator of the calcium sensing receptor (CaSR). Etelcalcetide hydrochloride is effective in lowering parathyroid hormone (PTH) concentrations in patients receiving dialysis with secondary hyperparathyroidism receiving hemodialysis, which is promising for research in the field of secondary hyperparathyroidism and chronic kidney disease.

Solvent & Solubility
H2O : 100 mg/mL (73.89 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
