Item #: ASIPG4AM

ION Biosciences IPG-4 AM

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

Higher K+ affinity than IPG-1 and IPG-2

ION Potassium Green – 4 (IPG-4) 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-4 has the highest affinity (Kd = 7 mM) among IPG analogues – IPG-2 (Kd = 18 mM) and IPG-1 (Kd = 50 mM).
