8-Nitroguanosine is a nitrated nucleic acid which is formed by peroxynitrite, myeloperoxidase, nitrite, and peroxide. It is known that nitration of guanine is enhanced in virus infection (1, 2), bacterial infection (3, 4), inflammatory disease (5), cancer (5), and diseases associated with smoking (6). 8-nitroguanosine is thought to be a DNA damage marker created by oxidative stress. Cyclic GMP (cGMP) is an important signaling molecule. Interestingly, 8-Nitro-cGMP (nitrated cGMP) has been identified in vivo (3). Therefore, 8-Nitro-cGMP could potentially act as a mediator for reactive oxygen signaling (3, 7-9).

Anti-Nitroguanosine polyclonal antibody does not cross-react with normal nucleobases but selectively reacts with nitrated nucleic acids such as nitroguanosine, nitroguanine, and nitroxanthine. Therefore, Anti-Nitroguanosine polyclonal antibody is a universal antibody against guanine modified 8th position with a nitro group. Anti-Nitroguanosine polyclonal antibody has very high affinity for 8-nitroguanine and 8-nitroguanosine, but it does not cross-react with normal guanosine, guanine, 8-hydroxyguanine or 3-nitrotyrosine. Since this antibody was prepared using rabbits, it can be used for immuno-histostaining of rodent tissues.
