We were happy to have Prof. Andriy Chmyrov (Helmholtz Zentrum München & NCT Dresden) as a guest speaker!
Thanks for joining us!

The setups will become part of the The Arenberg Optical Imaging Center (aoic.be) at KU Leuven.

It was 3D Fluorescence Imaging Inauguration Day today! 🥳

Together with the lab of Wim Vandenberg, we organized a launch event of two advanced custom-built 3D fluorescence microscopes! 🔬

High-Performance Chemigenetic Potassium Ion Indicator Potassium ion (K+) is the most abundant metal ion in cells and plays an indispensable role in practically all biological systems. Although there have been reports of both synthetic and genetically encoded fluorescent K+ indicators, there remains a need for an indicator that is genetically targetable, has high specificity for K+ versus Na+, and has a high fluorescent response in the red to far-red wavelength range. Here, we introduce a series of chemigenetic K+ indicators, designated as the HaloKbp1 series, based on the bacterial K+-binding protein (Kbp) inserted into HaloTag7 self-labeled with environmentally sensitive rhodamine derivatives. This series of high-performance indicators features high brightness in the red to far-red region, large intensiometric fluorescence changes, and a range of Kd values. We demonstrate that they are suitable for the detection of physiologically relevant K+ concentration changes such as those that result from the Ca2+-dependent activation of the BK potassium channel.

Ph.D. student Dazhou Cheng developed a chemigenetic K+ indicator (HaloKBP), using an rHCaMP/HaloCaMP-type design! pubs.acs.org/doi/10.1021/...
