T-cell Receptor (TCR) Sequencing Assay

TCR sequencing assay designed to interrogate V(D)J rearrangements in TCRβ and TCRy chains using RNA or total nucleic acids from whole blood or peripheral blood mononuclear cells (PBMC)

Our T- cell receptor sequencing assay targets and amplifies the TCR complementarity-determining region 3 (CDR3) and incorporates unique molecular indices to facilitate error correction and accurate counting of TCR clonotypes and their abundance and diversity at the mRNA level, using next generation sequencing on Illumina platforms. The TCR sequencing assay is part of our comprehensive immuno-oncology assay portfolio and is available for RUO or GCP applications.

  • Detects TCRβ and TCRy clonotypes that are actually expressed at the mRNA level
  • Molecular barcodes for error correction enable high accuracy and quantitative precision for tracking the dynamics of the T-cell repertoire over time
