iRT標(biāo)準(zhǔn)是11種自然中不存在的合成肽段的混合物。這些肽段經(jīng)過仔細(xì)地穩(wěn)定性、靈敏度甚至不同梯度下保留時間間隔的優(yōu)化。通過iRT試劑盒可以直接測定肽段的iRT值并用來校準(zhǔn)色譜系統(tǒng)。
使用iRT試劑盒校準(zhǔn)您的LC系統(tǒng)后,通過帶入更多的transition,可以大幅提高您靶向蛋白質(zhì)組(MRM和PRM)實驗的通量,甚至可達(dá)20倍。iRT標(biāo)準(zhǔn)帶來的好處對下一代蛋白質(zhì)組學(xué)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(zhì)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(shù)據(jù)分析,SpectroDive用于靶向蛋白質(zhì)組學(xué)實驗。
蛋白質(zhì)譜
蛋白質(zhì)譜技術(shù)是研究蛋白質(zhì)組學(xué)中新的一項技術(shù),它是通過蛋白酶將蛋白質(zhì)酶切消化后形成肽段混合物,在質(zhì)譜儀中將其電離形成帶電離子,并通過特定的質(zhì)荷比(m/z),進(jìn)而形成一級和二級質(zhì)譜,從而定量和鑒定蛋白。而在這的過程中,激發(fā)圖譜庫以及校準(zhǔn)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(biāo)準(zhǔn)的無綱量值。和傳統(tǒng)的保留時間不同,一個肽的iRT值是穩(wěn)定的并且可以用來在任何色譜條件下精確預(yù)測肽的保留時間。
iRT標(biāo)準(zhǔn)品是11種自然中不存在的合成肽的混合物。這些肽段經(jīng)過特定地穩(wěn)定性、靈敏度甚至不同梯度下保留時間間隔的優(yōu)化。通過iRT試劑盒可以直接測定肽段的iRT值,能校準(zhǔn)色譜系統(tǒng)并準(zhǔn)確預(yù)測目標(biāo)肽的保留時間。

使用步驟
iRT試劑盒用于時間分辨質(zhì)譜經(jīng)過兩個步驟:
1. 測定目標(biāo)肽段的iRT值與iRT標(biāo)準(zhǔn)品之間的關(guān)系
2. 使用iRT標(biāo)準(zhǔn)品校準(zhǔn)LC系統(tǒng),并準(zhǔn)確預(yù)測目標(biāo)肽段的保留時間
使用及包裝
1x iRT試劑盒包含:
• Dissolution Buffer (1x 2.0 ml tube)
• iRT Standard (1x 2.0 ml tube)
使用次數(shù)取決于樣品量及進(jìn)樣量,試劑盒適用于500次進(jìn)樣或50個樣品。
