Characterizing Exosomes with Next-Gen Protein Sequencing

This case study details the application of Next-Gen Protein Sequencing (NGPS™) technology in characterizing exosomes for therapeutic development. It outlines the challenges faced in detecting subtle protein variants and post-translational modifications, which are critical for understanding exosome biogenesis and their therapeutic effects. The study highlights KWEHEALTH's innovative approach of leveraging perinatal-derived exosomes from various sources to address rare diseases, particularly Prader-Willi syndrome. By utilizing the Quantum-Si Platinum® instrument, the team aims to sequence proteins in exosomes, allowing for a deeper understanding of production processes and the monitoring of therapeutic impacts through protein profile shifts. The case study also discusses the potential of NGPS to provide insights into protein variants associated with diseases like Parkinson's and its application in wound healing. Overall, the study emphasizes the importance of NGPS in ensuring consistent exosome production and advancing therapeutic modalities.
