Abstract

The Caenorhabditis elegans genome encodes a greatly expanded number of nuclear hormone receptors, many of which remain orphaned. Here, we present a protocol to assess ligand-receptor binding in C. elegans using an adapted cellular thermal shift assay and isothermal dose response. We describe steps for growing C. elegans and preparing lysates and compounds. We also detail how to perform and quantify these assays. This protocol can be used to study any soluble receptor. For complete details on the use and execution of this protocol, please refer to Peterson et al. (2023).1.
