Two high‑impact methods published this week promise to upend how labs read proteins. Stanford researchers detailed a scalable single‑molecule peptide sequencing approach that reverse‑translates amino acids into DNA barcodes for high‑resolution readout (Nature Biotechnology). Complementing that, another team reported a new protein‑sequencing platform that increases precision and throughput for complex proteomes. Together, the methods bridge proteomics and genomics workflows, enabling granular protein identification and potentially accelerating biomarker discovery and therapeutic target validation.
