Immunopeptidome Profiling

Investigate the dynamics and composition of Class I and Class II Immunopeptides

Deep characterization of the immunopeptidome can support the development of new therapeutics for cancer, immunological diseases, and infectious diseases. Biognosys’ Immunopeptidome Profiling solution consists of our proprietary, highly sensitive enrichment and identification of immunopeptides. We allow you to identify more than 10,000 Class I and 10,000 Class II peptides relevant for your drug discovery research.

    The immunopeptidome represents the entirety of peptides presented by nucleated cells on HLA or MHC Class-I and Class-II proteins involved in the antigen-presentation pathway. It is essential in defining immunogenic epitopes in cell-mediated and humoral responses. Characterizing the immunopeptidome will enable you to discover targets for personalized cancer immunotherapies, such as neoantigens from tumor-specific mutations or tumor-associated antigens. Furthermore, novel mRNA and peptide-based vaccines and cell-based therapies can be developed.

    We perform immunopeptidomics with our optimized high-throughput pipeline offering reproducible identification and quantification from minimal sample material.

    The service can be applied in large-scale studies and is ideal for researchers looking for a standalone solution that digs deep into what is unknown but ready to be discovered.

    “We were really impressed at the depth of peptide identification for both HLA I and II complexes from a small amount of cancer patient tissue. Thanks to quantitative MS, we can link biological hypothesis to quantification of neoantigen of interest.”
