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. Introduction Cell Biologists often need to detect and quantitate intracellular spectroscopically silent ions such as Cl-, Na+, K+, or Ca2+.
Ionized calcium binds to negatively charged sites on protein molecules, competing with hydrogen ions for the same binding sites on albumin and other calcium-binding proteins. This binding is pH dependent and alters the level of ionized calcium in the blood. An increase in pH, alkalosis, promotes increased protein binding, which decreases free calcium levels. Acidosis, on the other hand, decreases protein binding, resulting in increased free calcium levels.
