Product details
Catalog number 3021F
Price for 3021F
Size / count 10x 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.

Cross-reactivity data, based on available testing, is listed under the reactivity section of the datasheet. Contact us if you need reactivity confirmed for a species not listed.
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.
