Nitric oxide (No) is a reactive nitrogen species which is produced by nitric oxide synthase (NOS). NO is involved in many physiological processes including regulation of blood pressure, homeostasis, activation of immune system, neural communication, contraction of both smooth muscle and vascular tissue. Therefore, detection and quantification of NO is critical to understanding health and disease.The BioTracker SiRNO-Nitric oxide dye is a live cell near-infrared fluorescent imaging probe for detecting nitric oxide (NO). The probe targets NO specifically in the mitochondria and lysosome of living cells. The probe shows no cross reactivity to a variety of biomolecules and other reactive species including: ascorbic acid (AA), dehydroascorbic acid (DHA), methylglyoxal (MGO), GSH, Cys, Hcy, H2O2, ClO−, -OH, O2−, NO2−, and ONOO−. The SiRNO dye is pH insensitive in the range of 5.5 - 8.0, showing that it is suitable for physiological pH range. The SiRNO dye has been successfully used to detect NO in live cells, animal tissue and in vivo experiments.Spectral PropertiesAbsorbance: 633nmEmission: 650-750nm
