Fluo-4, AM

Introduction

Fluo-4, AM is a membrane permeant probe and can be passively loaded in cells by simple incubation. Once inside the cell, Fluo-4 becomes fluorescent in the presence of free Ca2+. Fluo-4 AM is widely used in flow cytometry, confocal laser scanning microscopy and fluorescence spectroscopy. Fluo-4, AM has proved particularly valuable for determining GPCR function via cell-based high-throughput screening.
Fluo-4, AM is supplied as 0.5 mg solid (C219), special packing 10×50 μg (C220), and 1 mg/ml solution in DMSO (C221).
