A robust and miniaturized screening platform to study natural products affecting metabolism and survival in Caenorhabditis elegans
Abstract In this study a robust, whole organism screening based on Caenorhabditis elegans is presented for the discovery of natural products (NP) with beneficial effects against obesity and age-related diseases. Several parameters of the elaborated workflow were optimized to be adapted for probing m...
