14178 IUPAC Gold Book - plate map 10.1351/goldbook.14178 14178 current 1 Layout of samples and controls configured on a plate during an assay. For a primary screen in 384-well plates, columns 1, 2, and/or 23 and 24 are controls, and the remaining columns are for individual test compounds. For secondary screening, more complex layouts are used and each row may contain a single compound at varying concentrations. PAC, 2011, 83, 1129.
