By collaborating with the scientific community, we've developed innovations that allow you to move away from bulk sample to single-cell proteomics analysis, which reveal the full complexity of cellular diversity. Single-cell proteomics by mass spectrometry (SCoPE-MS) is a recently introduced method to quantify multiplexed single-cell proteomes. While this technique has generated great excitement, the underlying technologies (isobaric labeling and mass spectrometry (MS)) have technical limitations with the po … Abstract. Single-cell proteomics refers to the analysis and characterization of proteins expressed in individual cells. The purpose of studying single-cell proteomes is to better understand the activity and function of cells at the single-cell level. A mature single-cell proteomics field will be a great benefit to many disciplines, but to achieve its full potential, advances beyond simple detection capacity are required. There are clear challenges that will become more pronounced as measurement technology improves.

Learn about the biggest technical challenges facing single-cell proteomics and how IsoPlexis helps overcome them. To increase throughput for single-cell proteomics analysis, the new TMTpro 16plex label reagent set delivers the ability to analyze more than 100 single cells per day per HRAM Tribrid MS instrument with the use of a booster channel to maximize sensitivity needed for single-cell analysis. Single-Cell Proteomics Single-Cell, Spatial Analysis for Discovery Biology Spatial phenotyping (via multiplex immunofluorescence) enables researchers to visualize and quantitate protein and biomarker expression to reveal how cells interact and organize across the entire tissue landscape. The future of advanced medicines relies upon deeper access to in vivo biology to create durable, curative impacts on disease. Our systems, which drive convergence of dynamic proteomics and single cell biology for the first time, are creating this deeper connection to accelerate curative medicines. Recent advances in single-cell analysis have unraveled substantial heterogeneity among seemingly identical cells at genomic and transcriptomic levels. These discoveries have urged scientists to develop new tools that are capable of investigating single cells from a broader set of “omics”.

Challenges and emerging directions in single-cell proteomics. Will It go mainstream like genomics? The Human Genome Project was a landmark achievement.

2020-05-04 The single cell proteomics meeting will bring together many of the pioneers in the field for sharing ideas, results, and informal discussions of future directions. We aim to create a forum for sharing knowledge and defining together the agenda of this new community. Many pressing medical challenges, such as diagnosing disease, enhancing directed stem-cell differentiation, and classifying cancers, have long been hindered by limitations in our ability to quantify proteins in single cells.

The recent growth in single-cell profiling has been focused primarily on nucleic acid measurement. To increase throughput for single-cell proteomics analysis, the new TMTpro 16plex label reagent set delivers the ability to analyze more than 100 single cells per day per HRAM Tribrid MS instrument with the use of a booster channel to maximize sensitivity needed for single-cell analysis. Single-Cell Proteomics Single-Cell, Spatial Analysis for Discovery Biology Spatial phenotyping (via multiplex immunofluorescence) enables researchers to visualize and quantitate protein and biomarker expression to reveal how cells interact and organize across the entire tissue landscape. Single-cell proteomics is a field in its infancy. The progress in measuring proteins from single cells stands in sharp contrast to progress in measuring nucleic acids.

How to handle subnanogram amounts of complex protein sample to digest them and transfer them to MS is more challenging. Single-cell Proteomics is broadly applicable to measuring proteome configurations of single cells and linking them to functional phenotypes, such as cell type and differentiation potentials.
