Nitric Oxide NO is a very important signaling molecule that acts in many tissues to regulate a wide range of physiological processes. It was first discovered several years ago by a group that was attempting to identify the agent responsible for promoting blood vessel relaxation and the regulation of vascular tone. This particular agent was named endothelium-derived relaxing factor EDRF, and was initially assumed to be a protein like most of the other signaling factors previously discovered. The discovery that EDRF was in fact nitric oxide, a small gaseous molecule, has led to many publications over the years including our Nytric EFX discovery. Our scientist found that besides promoting blood vessel relaxation and the regulation of vascular tone, NO plays a key role in many biological processes including immune defense, neurotransmission, and the regulation of cell death apoptosis. Since NO is such a very small molecule, it is able to diffuse rapidly across cell membrane and depending o
