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.
