一般說明

N-琥珀酰亚胺基-三(2,4,6-三甲氧苯基)磷基溴乙酸酯(TMPP-Ac-OSu)是一种酰化试剂,通常用于肽的N端α-氨基的选择性衍生化。即使不使用自动计算方法,TMPP乙酰化的肽也会发生断裂,从而产生a型离子,使获得序列信息变得更加容易。 在N端肽段的液相色谱偶联质谱(LC-MS/MS)分析中,它可以用作标记试剂,提高电离效率、简化片段化和保留时间,从而更好地分离肽段。

應用

在串联质谱法中,TMPP-Ac-OSu被用于标记肽,以便将精氨酸转化为鸟氨酸,从而改善肽的片段化模式。

包裝

无底玻璃瓶。内容物在插入式融锥内。

其他說明

肽 N-末端改性试剂,用于快原子轰击 (FAB) 或基质辅助激光解吸/电离质谱 (MALDI MS)

Imaging mass spectrometry (IMS) studies increasingly focus on endogenous small molecular weight metabolites and consequently bring special analytical challenges. Since analytical tissue blanks do not exist for endogenous metabolites, careful consideration must be given to confirm molecular identity. Here, we
