Product details
Catalog number 3021E
Price for 3021E
Size / count 3x 50 µg
ION Potassium Green - 4, potassium indicator, membrane permeable. Formerly known as Asante Potassium Green - 4 (APG-4). Compatible with a wide variety of detectors including fluorescent microscopes, plate readers, flow cytometers, and fluorescent indicator-doped solid-state sensors. Excitation: 525 nm | Emission: 545 nm | Kd: 7 mM | Purity: >95% The IPG family of indicators are the best-in-class replacements for the legacy K⁺ indicator, PBFI. Unlike PBFI, the spectral properties of the IPG family of K⁺ indicators make them convenient to use with common filter sets (e.g. YFP and FITC) as well as multiphoton approaches, and the range of K⁺ affinities make them useful for applications as diverse as extracellular K⁺ sensing to monitoring intracellular K⁺ dynamics. These molecules are small, synthetic fluorochromes which incorporate a K⁺-binding moiety. Under conditions where K⁺ is not bound, the fluorescence of the sensor is significantly quenched. When K⁺ is bound, the quenching is relieved, and the fluorescence of the sensor dramatically increases.

Animal-origin-free status, where applicable, is noted on the datasheet under formulation details.
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.
