dCODE Dextramer® (10x compatible)

Identify Antigen-specific T Cells and TCR Clonotypes at Single Cell Resolution

Identification of antigen-specific T-cell epitopes and their cognate T-cell receptors is key to the development of vaccines and immunotherapies. dCODE Dextramer® technology enables determination of T-cell antigen-specificity at single cell resolution, providing simultaneous information on T-cell receptor clonotypes and gene expression.

dCODE Dextramer® (10x compatible) reagents are DNA barcoded MHC Dextramer® reagents designed for use with 10x Genomics Feature Barcode protocol for Single Cell Immune Profiling. Each unique barcode is specific for the MHC-peptide displayed on the dCODE Dextramer®. dCODE Dextramer® also carries a PE-label for sorting and enrichment of rare cell populations.

dCODE Dextramer® reagents are designed for multiplexing, allowing identification of many different T-cell specificities in the same sample. Creating personalized dCODE Dextramer® libraries, it is possible to profile patients' T cells and get a new understanding of T-cell immunity.
