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.
“Biognosys is a valued partner of Grey Wolf Therapeutics across all departments for our immunopeptidomics research. Their technology and expertise have allowed us to define a signature for ERAP1 and ERAP2 inhibition in cancer cells and translate this knowledge into a pharmacodynamic biomarker. Together with Biognosys, we have demonstrated for the first time that the antigen repertoire can be changed by ERAP1 inhibition in cancer patients (ASCO 2024). The transition to DIA proteomics, established at Biognosys, has transformed the dynamic range of the PD biomarker, allowing us to see even the smallest of changes in patients. The breadth and quality of the data has convinced us that Biognosys is an industry leader in immunopeptidomics.”

“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.”
