Size / count 20x 50 μg
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.

Yes, if this product requires dry ice or is classed as hazardous for transport, the additional fee will be explicitly shown in your quotation before you confirm the order, so there are no surprise charges later.
We recommend aliquoting the product upon receipt to avoid repeated freeze-thaw cycles, which can reduce activity and stability. This is your responsibility once the product has been delivered.
Recommended antigen retrieval methods, where applicable, are listed on the datasheet under the IHC protocol section.
