Product Information

Easy-to-run, single-day assay that uses multiplex PCR-NGS technology to profile T-cell receptor (TCR) and / or B-cell receptor (BCR) repertoire starting from total RNA.

  • Profile all 4 TCR chains (TRA, TRB, TRG and TRD) and 3 BCR chains (IGH, IGK and IGL) in a single reaction from a single sample. 
  • Assay kits for profiling of only TCR (4 chains) or BCR (3 chains) also available. 
  • Includes all the enzymes, reagents, and primers to run single-tube, multiplex assays that generate NGS-ready libraries for 24- or 96- samples.
  • Optimized RT-PCR workflow. No specialized equipment required.  
  • Run in parallel with the DriverMap AIR TCR-BCR (Human DNA) kit with DNA starting material for insights into activated clonotypes
  • Data compatible with analysis using MiXCR (MiLabs) immune receptor profiling software and similar analysis packages.

Fig 1: Number of clonotypes for 7 TCR/BCR chains identified in 50ng of normal PBMC or whole blood RNA (10x10^6 reads per sample, triplicates).














Fig 2: Comparison of TCR clonotypes detected by DriverMap AIR RNA full-length assay vs SMART-based assay. Both assays were run with 50 ng total RNA isolated from PBMCs. Data shows that the DriverMap AIR RNA assay detects approximately 3X more TCR clonotypes than the SMART-based assay.


Comparison of CDR3 vs Full-Length Variable Region Repertoire Profiling

How it Works

The CDR3 region determines the structure and specificity of the antigen. The majority of repertoire profiling studies are based on the analysis of only the CDR3 region, as this is the hypervariable region and contains crucial information to study immune repertoire diversity.

The V region encodes CDR1 and CDR2 in germline DNA segments and primarily interacts with the major histocompatibility complex (MHC) molecules. The full-length receptor region is involved in antigen receptor binding affinity and/or downstream signaling and allows one to clone and express the identified and chosen receptors. 

Key Applications

  • Tracking T cell diversity and clonality

  • Finding markers of autoimmune diseases

  • Studying immune cell migration patterns

  • Antibody and vaccine development

  • T-cell epitope discovery
