MRM/PRM靶向蛋白質(zhì)組
定量蛋白質(zhì)組的結(jié)果(無論是標(biāo)記定量還是非標(biāo)記定量)往往需要通過其他的實(shí)驗(yàn)給予證實(shí)。傳統(tǒng)的蛋白質(zhì)組數(shù)據(jù)的驗(yàn)證通過基于抗體的分析方法(例如,Western blot或ELISA)。而多反應(yīng)監(jiān)測技術(shù)(multiple reaction monitoring,MRM)由于其獨(dú)特優(yōu)勢,成為了驗(yàn)證定量蛋白質(zhì)組數(shù)據(jù)的主要分析手段。
MRM/PRM技術(shù)集中表現(xiàn)在三大優(yōu)勢:
1. 基于質(zhì)譜信號響應(yīng)的定量信息遠(yuǎn)比基于圖像信號的定量分析更為準(zhǔn)確;
2. 一次MRM分析可完成多個靶標(biāo)蛋白質(zhì)的定量測定;
3. 實(shí)驗(yàn)費(fèi)用經(jīng)濟(jì),節(jié)省時間。
