Nature Biotechnology: User-Defined Peptide Libraries Enable Sensitive Detection of Cancer Antigens
A Nature Biotechnology paper introduced a user-defined peptide library platform that enables sensitive detection of cancer antigens — relevant for both cancer immunotherapy target identification and neoantigen vaccine design. The platform allows researchers to design peptide pools customized to specific tumor types or HLA profiles, accelerating the antigen-discovery bottleneck in personalized cancer vaccine development. Builds on the same proteomic technology stack advancing across multiple peptide-vaccine programs at BioNTech, Genentech, and emerging neoantigen biotechs.
