产品介绍：N-Succinimidyloxycarbonylmethyl tris(2,4,6-trimethoxyphenyl)phosphonium bromide (TMPP-Ac-OSu) is an acylating reagent, and is generally used for the selective derivatization of N-terminal a-amino group of peptide. The TMPP-acetylated peptides undergo fragmentation thereby creating a-type ions, thus obtaining sequence information becomes easier, even without the usage of automated computational approach. It can be used as a labelling reagent in liquid chromatography-coupled mass spectrometry (LC-MS/MS) of N-terminal peptides, so as to improve ionization efficiency, simplify fragmentation, and retention times, thereby leading to better separation of peptides.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)N-Succinimidyloxycarbonylmethyl tris(2,4,6-trimethoxyphenyl)phosphonium bromide (TMPP-Ac-OSu) is an acylating reagent, and is generally used for the selective derivatization of N-terminal a-amino group of peptide.
