Overview

Uncovering Exosome Heterogeneity through Combined Single-cell Proteome Sequencing

Exosomes are involved in a variety of physiological and pathological processes, and they also have great potential in the field of liquid biopsy. Except for exosomes derived from single cell culture medium, exosomes in body fluids and tissues are mixed sets and have very large heterogeneity. However, traditional exosome sequencing analyzes all exosome subsets and obtains the average result of all exosomes. This ignores or conceals individual differences in exosomes, and cannot fully capture the complexity, diversity, and differences in functions of exosomes. Single-cell proteome sequencing (scP-seq) can quantify all proteins expressed in a single cell, compare the types and contents of proteins between different single cells, and help to clarify the functional differences between cells. Most importantly, proteins are direct performers of biological functions within cells. Therefore, compared with single-cell transcriptome sequencing, scP-seq can reveal changes in protein expression in a single cell, revealing the nature of cellular regulation more directly. Therefore, the innovative combined analysis of scP-seq data and exosome proteome data will help provide evidence for the traceability of exosomes from the protein level.

Creative Biolabs can provide single-cell and exosome combined proteomics research service, helping customers to more accurately analyze the regulatory nature of exosomes from the protein level.

Single-Cell Proteomics and Exosome Proteomics Combined Research Service

Creative Biolabs innovatively extends protein analysis capabilities directly to the single-cell level. We can apply a microfluidic system that can simultaneously isolate 500-1500 single cells and combine it with antibody barcode array technology for scP-seq. scP-seq of tissue can analyze the tissue microenvironment from the two dimensions of cell subgroups and intercellular space exosomes, which can provide a basis for revealing the exosome communication network between cell subgroups in the tissue microenvironment. In addition, the combined scP-seq analysis of body fluid-derived exosomes and tissues can help to more accurately find key role proteins and disease marker proteins in exosomes.
