Immunopeptidomics
Find the antigens that matter, faster
Search immunopeptidomics data with the sensitivity and scale to uncover tumor-specific, non-canonical, and pathogen-derived antigens — demonstrated in independent academic research.
Why researchers choose Tesorai for immunopeptidomics
Purpose-built to find the antigens standard proteomics pipelines miss.
+60% is vs. all MaxQuant identifications; +136% is vs. the MaxQuant high-confidence subset, indexed separately.
Academic study source: NYU ImmunoVerse study, 21 cancer types (preprint)
More peptide identifications across cancer types
In a large-scale immunopeptidomics study spanning 21 cancer types, Tesorai Search increased peptide identifications by 60% on average compared with the MaxQuant baseline — and by 136% on average among high-confidence identifications.
28,446 tumor-specific HLA-presented antigens identified across 21 cancer types
Actionable tumor-specific targets found in 89% of tumors analyzed
Process massive datasets in hours, not weeks
In collaborator projects, Tesorai has reprocessed some of the largest public immunopeptidomics collections in the field, cutting turnaround from weeks of pipeline time to hours.
2,500 files analyzed in under 5 hours, vs. 8+ weeks with a legacy pipeline — in collaboration with NYU Langone Health & University of Notre Dame
~4,000 files (~4TB) reprocessed in ~7 hours using a custom 100,000-protein search database, in collaboration with Cincinnati Children's Hospital
Demonstrated in independent academic research
Tesorai's approach to immunopeptidomics search has been demonstrated in academic studies and large-scale collaborator projects — not just internal benchmarks.
“We extensively leveraged Tesorai to reprocess the public ImmunoVerse immunopeptidomics collection… completing the analysis in approximately 7 hours of total compute time… The superior accuracy of these predictions were reflected in comparison to ours and other prior validation studies.”
— Nathan Salomonis, Salomonis Lab, Cincinnati Children's Hospital
“We used to wait days to process thousands of files. Tesorai finished in just a few hours. It completely changes the pace at which we can operate.”
