一氧化氮（NO）比色检测试剂盒

Nitric Oxide (NO), produced endogenously from L-Arginine by nitric oxide synthetases, plays an important role in many physiological processes including vascular regulation, immune responses, and neural communication. NO is extremely unstable and undergoes repaid oxidative degradation to nitrite (NO2-) and nitrate (NO3-), which can be spectrophotometrically determined. ScienCell's Colorimetric Nitric Oxide Assay kit provides an accurate measurement of NO level in a simple two-step process: the reduction of nitrate to nitrite by vanadium (III) chloride, followed by quantification of nitrite by Griess reaction.

一氧化氮（Nitric Oxide, NO）由体内L-精氨酸在一氧化氮合酶（nitric oxide synthases）的作用下内源性生成，在多种生理过程中发挥重要作用，包括血管调节、免疫应答以及神经信号传递等。

NO极不稳定，在体内会迅速发生氧化降解，生成亚硝酸盐（NO₂⁻）和硝酸盐（NO₃⁻），二者可通过分光光度法进行测定。

ScienCell 比色法一氧化氮检测试剂盒采用简便的两步法实现NO水平的准确测定：首先在三价钒（V³⁺）氯化物作用下将硝酸盐还原为亚硝酸盐，随后通过Griess反应对亚硝酸盐进行定量检测。
