Sample multiplexing-based proteomic strategies rely on fractionation to improve proteome coverage. Tandem mass tag (TMT) experiments, for example, can currently accommodate up to 18 samples with proteins spanning several orders of magnitude, thus necessitating fractionation to achieve reasonable pro...

The phosphorylation of proteins modulates various functions of proteins and plays an important role in regulation of cell signaling. In the recent years, the label-free quantitative (LFQ) phos-phoproteomics has become the powerful tool to analyze the phosphorylation of proteins within the complex sa...

We evaluated the utility of a trimodal stationary phase (Trinity P1) in offline peptide fractionation, and found it performed similarly to ion exchange or high pH reversed phase based techniques. It is orthogonal to low pH reversed phase and uses MS compatible mobile phase solvents.

Proteome-wide abundance profiling across tissues can help to provide insight into the biological mechanisms underlying tissue-specific function and potential related dysfunction and amelioration thereof. Here, we use sample multiplexing to profile the proteomes of ten diverse mouse tissues using TMT...

Fractionation is essential to achieving deep proteome coverage for sample multiplexing experiments where currently up to 18 samples can be analyzed concurrently. However, prefractionation (i.e., upstream of LC-MS/MS analysis) with a liquid chromatography system constrains sample processing as only a...
