Establishment and validation of a 384-well antibacterial assay amenable for high-throughput screening and combination testing

A 384-well-based antibacterial assay amenable for high-throughput screening and combination testing is described. The assay uses 100-500 nL of test compounds and tolerates up to 2.5% dimethyl sulfoxide concentrations. It can be used for screening compound libraries and testing combinatory/synergistic/antagonistic effects of antibiotics, small molecules, and natural product extracts. (C) 2015 Elsevier B.V.
