Combine Antigen-specificity With Multi-omics Analysis

dCODE Dextramer® (RiO) reagents are DNA barcoded MHC Dextramer® products
designed to be compatible with BD RhapsodyTM Single-Cell Analysis System


Determine T-cell antigen-specificity at single-cell resolution, providing simultaneous information on gene expression and surface markers expression.

In this example, dCODE Dextramer® (RiO) and BD RhapsodyTM Single-Cell Analysis System were used to detect disease-specific CD4+ T cells within thousands of PBMC and to obtain their gene expression profiling at the single-cell level.

Read the Case Study

dCODE Dextramer® (RiO) identified EBV-positive T cells in a PBMC sample (left). The negative control dCODE Dextramer® did not detect any specific cells (right).

Perform simultaneous analysis of antigen specificity, transcriptomic profile, and surface protein expression.

  • High-avidity binding to T-cell receptors thanks to multiple MHC-peptide complexes
  • Massive multiplexing screening thanks to the unique barcode for each MHC-peptide specificity
  • Enrichment of low-frequency cells thanks to PE fluorochromes
  • Multiparametric analysis with BD RhapsodyTM Single-Cell Analysis System
