Biognosys iRT Kit——蛋白质谱利器
indexed retention time (iRT)是定义一个肽在特定类型填料(如C18)中的色谱保留时间相对于iRT标准的无纲量值。和经验保留时间不同,一个肽的iRT值是稳定的并且可以用来在任何色谱条件下精确预测肽的保留时间。
iRT标准是11种自然中不存在的合成肽段的混合物。这些肽段经过仔细地稳定性、灵敏度甚至不同梯度下保留时间间隔的优化。通过iRT试剂盒可以直接测定肽段的iRT值并用来校准色谱系统。
使用iRT试剂盒校准您的LC系统后,通过带入更多的transition,可以大幅提高您靶向蛋白质组(MRM和PRM)实验的通量,甚至可达20倍。iRT标准带来的好处对下一代蛋白质组学研究流程如DIA或SWATH来说同样重要。iRT肽段可以在您的DIA或SWATH检测中使高质量图谱库的生成及精确归一化成为可能。
iRT肽段需要与Biognosys软件同时使用:Spectronaut用于DIA或SWATH数据分析,SpectroDive用于靶向蛋白质组学实验。
蛋白质谱
蛋白质谱技术是研究蛋白质组学中新的一项技术,它是通过蛋白酶将蛋白质酶切消化后形成肽段混合物,在质谱仪中将其电离形成带电离子,并通过特定的质荷比(m/z),进而形成一级和二级质谱,从而定量和鉴定蛋白。而在这的过程中,激发图谱库以及校准肽保留时间(Retention Time)尤为重要。
iRT-indexed Retention Time是定义一个肽在特定类型填料(如C18)中的色谱保留时间相对于iRT标准的无纲量值。和传统的保留时间不同,一个肽的iRT值是稳定的并且可以用来在任何色谱条件下精确预测肽的保留时间。
iRT标准品是11种自然中不存在的合成肽的混合物。这些肽段经过特定地稳定性、灵敏度甚至不同梯度下保留时间间隔的优化。通过iRT试剂盒可以直接测定肽段的iRT值,能校准色谱系统并准确预测目标肽的保留时间。

使用步骤
iRT试剂盒用于时间分辨质谱经过两个步骤:
1. 测定目标肽段的iRT值与iRT标准品之间的关系
2. 使用iRT标准品校准LC系统,并准确预测目标肽段的保留时间
使用iRT试剂盒校准您的LC系统后,通过在一次的运行中带入更多的transition,可以显著提高靶向蛋白质组(MRM和PRM)实验的通量,其通量甚至可高达20倍。iRT标准品对下一代蛋白质组学研究流程如DIA或SWATH来说同样重要,其肽段可让DIA或SWATH检测中生成高质量图谱库。
使用及包装
1x iRT试剂盒包含:
• Dissolution Buffer (1x 2.0 ml tube)
• iRT Standard (1x 2.0 ml tube)
使用次数取决于样品量及进样量,试剂盒适用于500次进样或50个样品。
