General description
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.
Application
TMPP-Ac-OSu was used for labelling peptides, in tandem mass spectrometry, done for converting arginine to ornithine, in order to improve the fragmentation pattern of peptides.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.

We have recently reported a simple procedure by which low picomole quantities of peptides can be modified to the corresponding N-Tris(2, 4,6-trimethoxyphenyl)phosphonium-acetyl (TMPP-Ac) derivatives (Z. H Huang, J. Wu, D. A. Gage, and J. T. Watson, Anal. Chem. 69, 137-144
