Figure 1. Schematic diagram of the NOS activity detection In addition to detecting total NOS activity, this product can be combined with different NOS inhibitors to detect different subtypes of NOS. There are three isoforms of nitric oxide synthase NOS, neuronal (nNOS), inducible (iNOS), and endothelial cell type (eNOS), and all have various splice variants. NO produced by nNOS (also known as cNOS, bNOS, NOS-1, or type 1 NOS) in the central nervous system may play an important role in the storage of information related to learning and memory. And NO
