S-亚硝基硫醇被认为是一氧化氮的生物相关产物,参与这种自由基的许多不同活动。本文综述了目前蛋白质S-亚硝基硫醇的检测和分析方法。S-亚硝基硫醇检测的主要方法包括基于荧光的方法和基于开关的方法,每种方法都有不同的优点和注意事项。S-亚硝基硫醇的检测具有挑战性,并且容易出现许多伪影。准确的测量需要了解所涉及的方法的基本化学和使用适当的控制。对于一个研究领域来说,没有什么比普遍信任的稳健方法更重要了。S-Nitrosation领域已经开发出了这样的方法,但是由于S-亚硝基硫醇很容易作为人工产物引入,因此当前用户从过去的经验教训中吸取教训至关重要。
S-Nitrosothiols have been recognized as biologically-relevant products of nitric oxide that are involved in many of the diverse activities of this free radical. This review serves to discuss current methods for the detection and analysis of protein S-nitrosothiols. The major methods of S-nitrosothiol detection include chemiluminescence-based methods and switch-based methods, each of which comes in various flavors with advantages and caveats. The detection of S-nitrosothiols is challenging and prone to many artifacts. Accurate measurements require an understanding of the underlying chemistry of the methods involved and the use of appropriate controls. Nothing is more important to a field of research than robust methodology that is generally trusted. The field of S-Nitrosation has developed such methods but, as S-nitrosothiols are easy to introduce as artifacts, it is vital that current users learn from the lessons of the past.
