Proteins play a vital role in virtually all biological processes, serving as key regulators of cellular functions, disease biomarkers, and therapeutic targets. However, the identification, isolation, and characterization of proteins from biological specimens can be challenging due to their complexity and diversity. Next-Generation Protein Sequencing (NGPS) on Platinum® offers a groundbreaking approach to deeply interrogate individual proteins with high resolution on a user-friendly benchtop platform. When combined with protein separation or enrichment methods, Platinum enables characterization of individual proteins from biological samples, revealing crucial details such as amino acid variants and PTMs. In this application note, we demonstrate a method that combines Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) protein separation and NGPS on Platinum to identify and characterize serum proteins. This method holds potential for applications beyond serum, offering new insights into disease mechanisms and advancing therapeutic and diagnostic developments. Keep reading
