Title: assay validation Long Title: IUPAC Gold Book - assay validation DOI: 10.1351/goldbook.14109 Status: current Definition Experiments conducted to verify that the output measurements of the assay are consistently reflective of the activity against the target. Note Results are compared internally over multiple runs and externally (when available) to existing literature parameters such as \(K_{\rm{d}}\), \(K_{\rm{i}}\), \(K_{\rm{m}}\), or \(\pu{EC_{50}}\).
