product description

IPG-1 AM (Ion potassium green - 1), a fluorescent potassium indicator for intracellular applications banner

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)
