The purpose of this application note is to demonstrate the utility of the FLx800 fluorescence microplate reader to detect rapid changes in calcium ion concentration.

Calcitonin's physiological function as a regulator of blood calcium levels is relatively minor compared to the actions of PTH and calcitriol.
