102-Plex Approach for Accurate and Multiplexed Proteome Quantification

Numerous hyperplexing approaches have been developed to meet the demand for large-scale basic and clinical analysis. Currently, the analysis capacity has expanded to up to 54 samples within a single experiment by utilizing different isotopic and isobaric reagent combinations. In this report, we propose a super multiplexed approach to enable the analysis of up-to 102-plex samples within a single experiment. by the combination of our recently developed TAG-TMTpro and TAG-IBT16 labeling. We systematically investigated the identification and quantification performance of the 102-plex approach using the mixtures of E. coli and HeLa peptides. Our results revealed that all analyses demonstrated accurate and reliable quanti-fication performance. The combination of TAG-TMTpro and TAG-IBT16 approaches expands the multiplexing capacity to 102-plex, providing a more multiplexed quantification method for even larger-scale proteomic analysis.
