Nitric Oxide (NO) is an anti-bacterial and anti-viral effector of the innate immune system produced by activated immune cells such as monocytes, macrophages, neutrophils and natural killer (NK) cells. Microbial cell wall components and cytokines released from host cells can stimulate the production of inducible NO synthase (iNOS), which in turn generates NO.
The iNOS induction assay can be used to screen for compounds that induce or inhibit iNOS production in mouse macrophages.

Figure: iNOS induction assay. RAW 263.7 cells were treated with vehicle or LPS and IFN-g. After treatment, cell culture supernatants were assayed for total nitric oxide. Mean values are shown. Error bars represent standard deviations.
