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.
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.
The table below summarizes the key differences between profiling only the CDR3 region vs profiling of the full-length variable region.

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. |
