product description
Fluo-4 AM is the most popular green fluorescent, intracellular calcium indicator, and now it’s available at the highest purity grade (>98%) as Fluo-4 AM Ultrapure. Proven and trusted for decades to measure intracellular calcium flux in high throughput screening and fluorescence microscopy applications.
Fluorescence images of Fluo-4 AM stained cells before (-) and after (+) the addition of ionomycin, a calcium ionophore. Cellular fluorescence increases because of the influx of calcium.
