Exosomes Proteomics Research Solutions

Exosomes (Exosomes) are extracellular vesicles, and endocytosis secreted small membrane vesicles in cells. Exosomes are multivesicular vesicles with lipid bimolecular structures widely present in various body fluids (blood, urine, milk, etc.) and cell culture supernatants. Furthermore, exosomes also carry proteins, modified proteins, lipids, metabolites, nucleic acids (miRNAs, mRNAs), and other active substances. Exosomes and their contents play an essential role in antigen presentation, tumor cell development, and neurogenic signal transduction. Thus large-scale exosome proteomic analysis can support biomarker discovery and clinical diagnosis.

Data-independent acquisition (DIA) is a robust and reproducible proteomic technology for large-scale digital qualitative and quantitative research. The DIA mode divides the entire mass range into several sequential windows, and all precursor ions in each window were fragmented sequentially. Therefore, DIA overcomes the loss of low abundance peptide information for accurate quantification in the data-dependent acquisition (DDA) mode and avoids the drawback of targeted peptides in the selected reaction monitoring (SRM). An optimized throughput DIA workflow allowed for the efficient discovery and verification of candidate biomarkers simultaneously.

Our Exosomes Proteomics Research Solutions

Creative Proteomics uses DIA MS methods for proteomic analysis in biological fluid samples such as serum to assist your screening for potential candidate markers.




(1) As disease-specific biomarkers.
(2) Diagnostic and therapeutic strategies for metabolic and cardiovascular diseases, neurodegenerative diseases, and cancer.
