ION Biosciences Fura-2 LR AM
 

Leakage-resistant, ratiometric calcium (Ca²+) indicator, membrane permeable.

 

UV-excitable, ratiometric green indicator for intracellular calcium (Ca²+) measurements with longer cellular retention compared to Fura-2 AM and similar spectral properties. Ex/Em: 340/505 nm can be used to measure Ca²+-bound Fura-2, and Ex/Em: 380/505 nm can be used to detect Ca²+-free Fura-2. Ratiometry is optimal for imaging applications where quantification of intracellular Ca²+ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.

ION Biosciences RATIOMETRIC CALCIUM ESSENTIALS
 

Ratiometric Calcium Essentials kit provides the necessary reagents for conducting no wash, ratiometric calcium flux assays compatible with plate reader and fluorescence microscopy applications. Individual components are provided to give the user the flexibility needed to customize your assay.
 

Fura-2 is the most popular UV-excitable, ratiometric green indicator for intracellular calcium (Ca²+) measurements. Ex/Em: 340/505 nm can be used to measure Ca2+-bound Fura-2, and Ex/Em: 380/505 nm can be used to detect Ca²+-free Fura-2.
 

Ratiometry is not only optimal for imaging applications where quantification of intracellular Ca²+ concentrations is desired, it also reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.

ION Biosciences Fura-2 K+ Salt
 

Ratiometric calcium (Ca²+) indicator, membrane impermeable.

Ex/Em: 340/505 nm can be used to measure Ca²+-bound Fura-2, and Ex/Em: 380/505 nm can be used to detect Ca²+-free Fura-2. Ratiometry is optimal for imaging applications where quantification of intracellular Ca²+ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.

 

Fura-2 K+ salt is a membrane impermeable form of Fura-2 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
