Complexome profiling is a rapidly spreading, powerful approach to gain insight into the nature of protein complexes. It identifies and quantifies protein complexes separated into multiple fractions of increasing molecular mass using mass spectrometry-based, label-free bottom-up proteomics. Complexom...
Although tandem mass tag (TMT)-based isobaric labeling has become a powerful technique for multiplexed protein quantitation, it has not been easy to automate the workflow for widespread adoption. This is because preparation of TMT labeled peptide samples involves multiple steps ranging from protein ...
A popular method for peptide quantification relies on isobaric labeling such as tandem mass tags (TMT) which enables multiplexed proteome analyses. Quantification is achieved by reporter ions generated by fragmentation in a tandem mass spectrometer. However, with higher degrees of multiplexing, the ...
We established a workflow for highly sensitive multiplexed quantitative phosphoproteomics using a nano-scale solid-phase tandem mass tag (TMT) labeling reactor. Phosphopeptides were firstly enriched by titanium oxide chromatography and then labeled with isobaric TMT reagents in a StageTip packed wit...
