Exosomes

Isolation techniques for exosomes are demanding; however, it is critical to understand the composition of the vesicles in your preparation. Biases can be introduced during sample preparation, such as: DNA, RNA, protein, and lipid extraction; PCR amplification; library preparation; sequencing; and/or data interpretation. To overcome these challenges, ATCC offers exosomes derived from well-authenticated cell lines and hTERT-immortalized Mesenchymal Stem Cells. These extracellular vesicles can be used as standards for creating diagnostic tests and studying exosome composition, epigenetic reprogramming of cells, and disease markers.
