SBFI K+ Salt - green fluorescent sodium indicator
Ratiometric sodium indicator, membrane impermeableExcitation: 340, 380 nm | Emission: 505 nm | Kd: 5 mMSBFI is a UV-excitable, ratiometric green indicator for intracellular sodium (Na⁺) measurements. Ex/Em: 340/505 nm can be used to measure Na⁺-bound SBFI, and Ex/Em: 380/505 nm can be used to detect Na⁺-free SBFI. It is ~18X more selective for Na⁺ over K⁺. Ratiometry is optimal for imaging applications where quantification of intracellular Na⁺ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.SBFI K⁺ salt is a membrane impermeable form of SBFI that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.

IPG-2 TMA+ Salt - yellow-green fluorescent potassium indicator
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.

ICR-1 K+ Salt - red fluorescent calcium indicator
ION Calcium Red-1. Red fluorescent calcium indicator, membrane impermeable. Optimal for multiplexing and tissue imaging.Excitation: 580 nm | Emission: 660 nm | Kd: 480 nM | Purity: >95%ION Calcium Red - 1 (ICR-1) is a red fluorescent (Ex/Em 580nm/660nm) calcium (Ca²⁺) indicator for intracellular Ca²⁺ measurements. ICR-1's long-wavelength emission and a large Stokes shift reduces contributions of autofluorescence, making ICR-1 AM optimal for cellular and tissue imaging applications. ICR-1 can also be multiplexed with GFP-labeled cells or other green fluorophores commonly used in experiments. Unlike some other red fluorescent Ca²⁺ indicators, ICR-1 does not accumulate in the mitochondria. Data supporting fluorescence lifetime imaging and multiphoton imaging capabilities have also been demonstrated.ICR-1 K⁺ salt is a membrane impermeable form of ICR-1 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
