This workshop presents a suite of technologies overcoming challenges when studying antigen-specific immunity, identify rare antigen-specific immune cells with confidence and at scale, activate and proliferate antigen-specific T cells (Xynapse-T technology), find the needle in the haystack – massive multiplexing on B and T cells (dCODE Technology), characterize TCRs – specificity, cross reactivity, affinity ranking, profile Immune Cell Repertoire in disease or treatment (flow, single cell multiomics)
