Protein barcoding has emerged as a transformative tool for the multiplexed identification and characterization of proteins, providing a mechanism for precise tracking of protein affinity, location, and expression. In this study, we describe the development of a protein barcoding workflow for use with single-molecule Next-Generation Protein Sequencing (NGPS) on the benchtop Platinum instrument.
This paper presents data on the validation of eight peptide barcodes, each designed to minimize detection bias and maximize sensitivity across various experimental conditions.
The Platinum instrument, kits, and software contain everything you need to prepare, sequence, and analyze proteins. The Barcoding Kit is a new initial step in Quantum-Si’s Next-Generation Protein Sequencing workflow. The Barcoding Kit prepares and immobilizes barcode-tagged peptides for sequencing.
The Platinum instrument fits on your benchtop and seamlessly integrates into your existing workflow, enabling protein sequencing right after sample preparation and chip loading.
Equipped with a user-friendly interface, Platinum allows you to easily start your protein sequencing run following a few prompts. Sequencing data is generated and can be automatically transferred to the Platinum Analysis Software for analysis.
