Ratiometric potassium indicator, membrane permeable Excitation: 340, 380 nm | Emission: 505 nm | Kd: 5 mM PBFI is a UV-excitable, green ratiometric 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 Na⁺, and 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.

If you’re outside the EU, UK, or USA, you’re responsible for customs clearance and any related taxes or fees. We provide the standard import documents, such as the Commercial Invoice, Packing List, and Airway Bill, in advance, so let us know early if your customs office needs anything additional for this specific product.
The formulation or storage buffer is listed on the product datasheet. If you require a carrier-free or custom formulation, contact us before ordering, as this may involve a made-to-order production timeline.
A starting IHC dilution range is listed on the datasheet, but should be optimized for your specific tissue type and staining protocol.
