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+.
The effect of this signaling of high extracellular calcium results in an intracellular calcium concentration that inhibits the secretion of preformed PTH from storage granules in the parathyroid gland. In contrast to the mechanism that most secretory cells use, calcium inhibits vesicle fusion and release of PTH.
