product description

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

IPG-1 TMA⁺ salt is a membrane impermeable form of IPG-1 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
