Invitrogen™ Calcium Orange™, AM, cell permeant - Special Packaging

Labeled calcium indicators are molecules that exhibit an increase in fluorescence upon binding Ca²⁺. They have uses in many calcium signaling investigations, including measuring intracellular Ca²⁺, following Ca²⁺ influx and release, and multiphoton excitation imaging of Ca²⁺ in living tissues. Cells may be loaded with the AM ester forms of these calcium indicators by adding the dissolved indicator directly to dishes containing cultured cells. The fluorescence signal from these cells is generally measured using fluorescence microscopy, fluorescence microplate assays, or flow cytometry
