dCODE Dextramer® (HiT)

Identify Multiple Antigen-specific T Cells in One Sample

The immune response is complex and not always restricted to one antigen or a single cell surface marker. The human T-cell repertoire is vast and comprises more than 107different T-cell receptors (TCRs), each of them able to detect up to 106 sequence variations of a peptide. The extreme diversity of the TCR repertoire represents a major analytical challenge and requires T-cell monitoring assays that are able to measure multiple parameters at the time. 

dCODE Dextramer® (HiT) carries a unique DNA barcode, coding for the MHC-peptide specificity displayed on the Dextramer. The MHC-peptide specificity displayed on a cell-binding dCODE Dextramer® (HiT) molecule can be identified by PCR and sequencing of the attached DNA barcode.

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