iRT標準是11種自然中不存在的合成肽段的混合物。這些肽段經過仔細地穩定性、靈敏度甚至不同梯度下保留時間間隔的優化。通過iRT試劑盒可以直接測定肽段的iRT值并用來校準色譜系統。
使用iRT試劑盒校準您的LC系統后,通過帶入更多的transition,可以大幅提高您靶向蛋白質組(MRM和PRM)實驗的通量,甚至可達20倍。iRT標準帶來的好處對下一代蛋白質組學研究流程如DIA或SWATH來說同樣重要。iRT肽段可以在您的DIA或SWATH檢測中使高質量圖譜庫的生成及精確歸一化成為可能。
iRT肽段需要與Biognosys軟件同時使用:Spectronaut用于DIA或SWATH數據分析,SpectroDive用于靶向蛋白質組學實驗。
蛋白質譜
蛋白質譜技術是研究蛋白質組學中新的一項技術,它是通過蛋白酶將蛋白質酶切消化后形成肽段混合物,在質譜儀中將其電離形成帶電離子,并通過特定的質荷比(m/z),進而形成一級和二級質譜,從而定量和鑒定蛋白。而在這的過程中,激發圖譜庫以及校準肽保留時間(Retention Time)尤為重要。

iRT kit
iRT-indexed Retention Time是定義一個肽在特定類型填料(如C18)中的色譜保留時間相對于iRT標準的無綱量值。和傳統的保留時間不同,一個肽的iRT值是穩定的并且可以用來在任何色譜條件下精確預測肽的保留時間。
iRT標準品是11種自然中不存在的合成肽的混合物。這些肽段經過特定地穩定性、靈敏度甚至不同梯度下保留時間間隔的優化。通過iRT試劑盒可以直接測定肽段的iRT值,能校準色譜系統并準確預測目標肽的保留時間。

使用步驟
iRT試劑盒用于時間分辨質譜經過兩個步驟:
1. 測定目標肽段的iRT值與iRT標準品之間的關系
2. 使用iRT標準品校準LC系統,并準確預測目標肽段的保留時間
