ION Biosciences IPG-1 AM

Yellow-green fluorescent, potassium (K+) indicator, membrane permeable.
 

Lower K+ affinity than IPG-2 and IPG-4.
 

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).
