Figure 1. The Oncomine TCR Beta-SR Assay targets the complementarity-determining region 3 (CDR3) within the TCR beta chain locus. The assay consists of multiplexed primers that bind to framework region 3 (FR3) and joining regions of the locus, producing amplicons approximately 80 bp in length for sequencing. TCR: T-Cell receptor
