83-1164-39　IPG-2 TMA+ Salt - yellow-green fluorescent potassium indicator 10 x 50 ug　3013F

特徴

• ION Potassium Green - 2, potassium indicator, membrane impermeable.
• Formerly known as Asante Potassium Green - 2 （APG-2）.
• 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： 18 mMThe 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.IPG-2 TMA⁺ salt is a membrane impermeable form of IPG-2 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
