General description

Calcium (Ca2+) play a vital role in the physiology and biochemistry of the cell. Calcium ions play an important role in signal transduction pathways, neurotransmitter release from neurons, contraction of all muscle cell types, and in fertilization. Extracellular calcium is also important for maintaining the potential difference across excitable cell membranes, as well as proper bone formation.

The BioTracker 664 NIR Ca2+ Dye is a live cell far-red fluorescent calcium indicator. The dye changes fluorescent intensity greatly (1000-fold) when it binds to calcium. Multicolor imaging is possible between the dye and Hoechst, Fluorescein, Rhodamine, GFP, YFP and RFP etc., which are fluorescent probes or fluorescent proteins having fluorescent wavelength from UV region to visible area. The advantages of long wavelength region are greater tissue penetration and low phototoxicity.
BioTracker 664 NIR Ca2+ Dye can be introduced by microinjection, patch clamp and electroporation. BioTracker 664 NIR Ca2+ AM Dye is an acetoxymethyl ester version and can permeate cell membranes.
