ION Biosciences' Brilliant Thallium Gold Assay Flex kit is a total assay solution for multi-well plate-based, high-throughput measurements of Tl+ flux through K+, Na+, non-selective cation channels, and some Na+ or K+ transporters. The kit includes our proprietary Thallos Gold indicator (Ex/Em: 530/546 nm), which is responsive to intracellular Tl+ dynamics. Thallos Gold’s spectral properties allow for multiplexing with GFP-expressing cells or other green-fluorescent indicators, and will help mitigate false positives caused by auto-fluorescent compounds within a library. The ION Biosciences Brilliant Thallium Gold Assay is also useful for a wide range of effectors of ion channels and transporters including G protein-coupled receptors, lipid kinases and protein kinases. 10\ plate kit.
