质谱(Mass Spectrometry, MS)是一种常用的分析技术,可用于定量和定性分析化合物。MRM (Multiple Reaction Monitoring) 是质谱中的一种常见技术,用于定量分析目标化合物。绘制标准曲线是使用MRM技术进行定量分析的重要步骤之一。 下面是关于如何绘制质谱MRM标准曲线的详细步骤: 1. 准备标准溶液,首先,准备一系列已知浓度的...
解释:SRM是MRM的另一种表述方式,两者在质谱分析中的应用原理相同,都是基于已知或假定的反应离子信息进行数据选择。 Targeted Mass Spectrometry:目标导向质谱法,强调对特定目标的质谱分析。 解释:虽然不完全等同于MRM,但目标导向质谱法也强调对特定分析物的选择性检测,与MRM技术有相似之处。 Tandem Mass Spectrometry wi...
Monitoring Post-Translational Modifications in Human Gamma S-Crystallin by Multiple Reaction Monitoring (MRM) Mass SpectrometryMRM can be used to rapidly analyze multiple sites of deamidation in aged human lenses. For the peptides analyzed, MRM results confirm that deamidation is more prevalent in the...
相比较 与我们熟悉的鸟枪法技术shot-gun有所区别,质谱蛋白质组学定向分析技术(targeted proteomics analysis by mass spectrometry)能够非常灵敏的检测到蛋白质信号,而且实验重复性也非常高。相比较之下,鸟枪法是将从一个蛋白质组样品里检出的所有质谱信号与现有的蛋白质数据库进行比对,从而对这些信号进行解析。 定向蛋白...
MRM (Multiple Reaction Monitoring) is a targeted mass spectrometry acquisition mode, and the mainstream method in this regard, commonly used for relative or absolute quantification of peptides or other small molecules. With a wide linear dynamic range, and excellent sensitivity, accuracy, and reproduc...
