- Fluorescence Alternatives to Popular Biological Assays: Caco-2, hERG, Radioligand Binding, and Chromium Release
Product News: Fluorescence Alternatives to Popular Biological Assays: Caco-2, hERG, Radioligand Binding, and Chromium ReleaseAs science evolves, new technologies and methods are continuously created that supplant older, outdated methods. The main reasons to replace outdated applications are: to save money, to save time, and to be safer. If a new application can do all three, its chance of successfully replacing an older technology greatly increases.
In the last decade, the microplate reader has become a multi-mode, multi-functional instrument that is used routinely in most laboratories. As such, the number and type of microplate based applications have grown tremendously. A number of these applications use the Fluorescence Intensity, Fluorescence Polarization or Time-Resolved Fluorescence detection mode in a microplate reader. These fluorescent based applications tend to be more cost effective as well as safer than classic radioactive applications. Here we highlight four classic applications that can be measured on one instrument using fluorescence detection methods.
Now with the PHERAstar FS microplate reader from BMG LABTECH, there are safer, faster, and more cost-effective alternatives to the Caco-2 cell-based assay, the hERG patch clamp binding assay, receptor radioligand binding assays, and the radioactive chromium release assay (to name a few). Money will be saved by not buying specialized equipment for each assay. Time will be saved compared to whole cell Caco-2 assays and patch clamp hERG binding assays. In addition, fluorescence material is safer and less expensive than radioactive material for receptor binding or chromium release cytotoxicity assays. Details of these alternative applications can be found in several PHERAstar FS application notes.
These are just a few of the many fluorescent applications that have been developed on the PHERAstar series of microplate readers. The flexibility, sensitivity, and multi-functionality of the PHERAstar enables microplate based applications that were previously not possible.
