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...
This study aimed to compare the depth and reproducibility of total proteome and differentially expressed protein coverage in technical duplicates and triplicates using iTRAQ 4-plex, iTRAQ 8-plex and TMT 6-plex reagents.
The multiplexing capabilities of isobaric mass tag based protein quantification, such as Tandem Mass Tags (TMT) or Isobaric Tag for Relative and Absolute Quantitation (iTRAQ) have dramatically increased the scope of Mass Spectrometry (MS) based proteomics studies. Not only does the technology allow ...
About “MS210144-1 to MS210144-12”: 6 samples: cell body-1#, cell body-2#, cell body-3#, Migrasome-1#, Migrasome-2#, Migrasome-3#, were labeled with tandem mass tags (TMT) reagents and then mixed. These combined TMT-labeled peptides were separated into 12 fractions (shown in list: from MS210144-1 to ...
Pediatric obstructive sleep apnea (OSA) is a frequent respiratory disorder with an estimated prevalence of 3–6% in the general population. However, the underlying pathophysiology of OSA remains unclear. Recently, proteomic analysis using high-resolution and high-throughput mass spectrometry has been...
Recent advances in mass spectrometry now allow unbiased proteome profiling of thousands of proteins from single cells using both label-free and labeling approaches. However, a major limitation of unbiased approaches is missing data, which worsens as the sample size increases. In addition, the reprod...

Here, we present an RNA-specific isobaric tandem mass tagging (RMT) approach that enables the quantitative mapping of RNA modifications at an omics scale with high chemical accuracy. These RNA mass tags, derived and optimized from proteomics isobaric tags, are incorporated into an end-to-end workflo...
