IPG-1 TMA+ Salt | B3141

IPG-1 is a small, synthetic fluorochrome which incorporates a K⁺-binding moiety. When K⁺ binds, the quenching is relieved and the fluorescence dramatically increases. 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 (Cat. Nos. B3142, B3143; Kd = 18 mM) or IPG-4 (Cat. Nos. B3144, B3145; Kd = 7 mM). IPG-1 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.
