This product is air and light sensitive and impurities can occur as a result of air oxidation or due to metabolism by microbes. description： A highly sensitive and specific fluorescent indicator for the direct detection of nitric oxide (NO) in vitro. The relatively non-fluorescent DAF-2 reacts rapidly with NO in the presence of oxygen to yield the highly fluorescent triazolofluorescein compound (DAF-2T). Can detect NO under neutral conditions (detection limit = 5 nM). A highly sensitive and specific fluorescent indicator for the direct detection of nitric oxide (NO) in vivo. The relatively non-fluorescent DAF-2 reacts rapidly with NO in the presence of oxygen to yield the highly fluorescent compound triazolofluorescein (DAF-2 T). Can detect NO under neutral conditions (detection limit = 5 nM). Excitation maximum: 495 nm; emission maximum: 515 nm.
