PMQA is an 8-aminoquinoline-based ratiometric fluorescent sensor designed for the detection of zinc ions (Zn2+). Upon interaction with Zn2+, PMQA exhibits a significant redshift in emission wavelength (85 nm), facilitating sensitive measurements. This cell membrane-permeable probe is suitable for real-time imaging of Zn2+ in living cells, making it valuable for studies in cellular signaling and zinc homeostasis.
