LC-MS/MS is a powerful analytical technique that provides unequivocal identification and reliable quantification of the analytes, using Selected Reaction Monitoring or Multi Reaction Monitoring acquisition mode.Anandamide (N-arachidonoylethanolamine, AEA) and 2-Arachidonoylglycerol (2-AG) are the most abundant endocannabinoids (eCBs), which play a major role in a wide variety of physiological and pathological processes. Analysis of those compounds by means of LC-MS/MS allows the detection of very low concentrations in biological samples. Here, we describe how to determine AEA and 2-AG levels in tiny samples of tissues and plasma through LC-MS/MS, by using very quick and easy-to-perform extraction procedures, with reduced solvent consumption.
LC-MS/MS 是一种强大的分析技术,可使用选择反应监测或多重反应监测采集模式,提供分析物的明确鉴定和可靠定量。花生四烯酸乙醇胺(N-花生四烯酸乙醇胺,AEA)和 2-花生四烯酸甘油(2-AG)是最丰富的内源性大麻素(eCBs),它们在广泛的生理和病理过程中发挥主要作用。通过 LC-MS/MS 分析这些化合物可在生物样本中检测到非常低的浓度。在这里,我们描述了如何通过 LC-MS/MS 以非常快速且易于执行的提取程序,在组织和血浆的微小样本中检测 AEA 和 2-AG 水平,同时减少溶剂消耗。
