Novel Fluorescent Probes for Ratiometric (Sub)cellular K+ Imaging

GEPIIs – genetically encoded potassium ion indicators (GEPIIs) allow the (sub)cellular (cytosol, nucleus and mitochondria) imaging of K+ dynamics [Bischof et al. Nature Communications 2017] . Here we provide ready-to-use GEPII-encoding plasmids and related products in high quality for K+ imaging and K+ quantification experiments:
