product description

ION Potassium Green – 2 (IPG-2) is a yellow-green fluorescent, intracellular potassium (K⁺) indicator with Ex/Em: 525 nm/545 nm and a high-sensitivity to detect small changes in K⁺ concentration. IPG-2 has a higher affinity (Kd = 18 mM) than IPG-1 (Kd = 50 mM) and lower affinity than IPG-4 (Kd = 7 mM).

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.
