Optimized incubation regime for nitric oxide measurements in murine macrophages using the Griess assay

The Griess assay is used to measure nitric oxide concentrations in liquid solutions after reaction into nitrite. The assay is challenging when applied to cell culture supernatants. During optimization, we focused on the anti-inflammatory potential of test compounds in murine RAW264.7 macrophages. This led to (i) the required inductivity of cells by lipopolysaccharide (LPS) and allowed (ii) the characterization of putative anti-inflammatory test...
