Product Description
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. It is a small, synthetic fluorochrome which incorporates a K⁺-binding moiety. When K⁺ binds, the quenching is relieved and the fluorescence dramatically increases. IPG-2 has a higher affinity (Kd = 18 mM) than IPG-1 (Cat. Nos. B3140, B3141; Kd = 50 mM) and lower affinity than IPG-4 (Cat. Nos. B3144, B3145; Kd = 7 mM). IPG-2 TMA⁺ salt is a membrane impermeable form of IPG-1 that can be used in lipid membrane-free systems, liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
