has detection method has endpoint has assay method is measure group of has role has participant bioassay physical detection method measure group Measure group is used to group and link multiple (different) sets of experimental results to one bioassay. Measure groups thus facilitate the description of multiparametric (or multiplexed) assays, that measure more than one effect of the perturbagen on the system that is screened. It also facilitate the definition of panel and profiling assays, e.g. assays that test compounds against multiple (protein) targets. Compare definition of bioassay. Measure group links to those classes that can vary among different measurements of a panel assay, profiling assay, multiparametric assay, e.g. target, assay design method, physical detection method, endpoint. Measure group is also used to define derived endpoints, for example concentration-response endpoints obtained by curve fitting a set of results from the same compound tested in the same assay at different concentrations. screened entity result endpoint measured entity assay design method molecular entity target biological macromolecule assay bioassay component
