PBFI K+ Salt
ION Biosciences PBFI K+ Salt
 
PBFI is a UV-excitable, ratiometric green indicator for intracellular potassium (K+) measurements. Ex/Em: 340/505 nm can be used to measure K+-bound PBFI, and Ex/Em: 380/505 nm can be used to detect K+-free PBFI. It is 1.5X more selective for K+ over Naand works well in cytosolic conditions where [K+]/[Na] is ~10. Ratiometry is optimal for imaging applications where quantification of intracellular K+ concentrations is desired and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.

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