Applications for TCR Repertoire Profiling: Bridging the Gap between Repertoire Frequency and Functional Specificity
This session explores end-to-end workflows for identifying tumor-reactive T cells.
- After a brief introduction to Cellecta's technologies presented by Paul Diehl, Cellecta chief operating officer, Alex Chenchik, Cellecta president and chief scientific officer, will discuss how to leverage Cellecta’s DriverMap AIR TCR profiling assays to detect antigen-expanded TCRs using bulk and single-cell sequencing to obtain chain-pairing information.
- Next, our invited speaker, Katharina Lindner, from the German Cancer Research Center (DFKZ), will introduce ESPEC-SUIT, a platform developed to bridge the gap between repertoire frequency and functional specificity. She will demonstrate the workflow by longitudinally tracking antigen-specific clonotypes across blood and tumor compartments in neoepitope-vaccinated glioma patients.
- By combining sensitive TCRβ sequencing with functional validation, our speakers show how characterizing TCR dynamics uncovers mechanisms of tumor rejection and resistance, accelerating the discovery of potent, tumor-reactive TCRs for immuno-oncology.

From Repertoire to Response: A Workflow for Mapping Antigen-Driven T and B Cell Clonotypes
We will present an integrated immune profiling workflow that links repertoire sequencing with functional validation to rapidly identify antigen-specific T and B cell clonotypes. By combining bulk and single-cell AIR profiling with multiplexed receptor pairing and reporter-based screening, it enables high-confidence epitope discovery for immuno-oncology applications, biomarker development, and targeted immunotherapy design.

Identification and Tracking of Antigen-Specific T Cell Receptors in Cancer Patients by High-Throughput TCR Sequencing
Granular profiling of antigen-specific T cell receptor (TCR) repertoires remains a challenge in cancer immunology. We describeESPEC-SUIT, a sequencing-based platform integrating peptide-drivenin vitro expansion of antigen-specific CD4⁺ and CD8⁺ T cells with TCR repertoire analysis. Antigen-stimulated cultures undergo bulk TCRβ sequencing to define expanded clonotypes, enabling downstream tracking, cloning and functional validation of TCRs. Applied longitudinally, ESPEC-SUIT captures dynamic changes in antigen-specific TCR repertoires and supports tracking of clonotypes across blood and tumor samples, which we demonstrate in a cohort of neoepitope-vaccinated glioma patients. ESPEC-SUIT enables scalable, comprehensive, and sensitive interrogation of tumor-reactive TCR landscapes for immuno-oncology research.
