ION Biosciences’ Flow Cytometric Potassium Channel Assay is the first assay solution for single-cell, high-throughput measurements of potassium channel activity. Powered by our patent-pending Snapshot assay technology, ion channel modulation generates a long-lasting signal so you can easily detect and quantify changes in ion channel or transporter activity using Flow Cytometry. This kit may also work for sodium channels, non-selective cation channels, and some Na+ or K+ transporters. 200 assays. Excitation: 490 nm | Emission: 515 nm
