ION Potassium Green - 4, potassium indicator, membrane impermeable. 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 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. IPG-4 TMA⁺ salt is a membrane impermeable form of IPG-4 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.

The expression system, such as E. coli, HEK293, or insect cells, is listed on the datasheet under production details, which can affect post-translational modifications relevant to your application.
As a consumer, you have a 14-day right of withdrawal from receipt under EU consumer protection law, submitted via our withdrawal/cancellation request form. Note this applies to unused, undamaged products, and doesn’t override the expiry/storage conditions on performance-based claims.
Endotoxin testing status is noted on the datasheet where applicable, particularly for recombinant proteins intended for cell-based or functional assays. If this isn’t listed and you need confirmation, contact support with the catalogue number.
