By integrating scRNA-seq and TCR repertoire analysis, gene expression information and TCRα/β pair sequences necessary for clone reconstitution can be simultaneously analyzed for individual T cells. Based on the characteristics and frequency of each clone, it is possible to narrow down clones that are promising for TCR gene therapy and other applications.
* For TCR repertoireanalysis, please also refer to the TCR repertoire analysis page. Here, TCR repertoireanalysis is performed at the single cell level.
Single-cell RNA-seq is available with either whole transcriptome amplification (WTA) or targeted sequencing using BD's Immune Response Panel.
*Target sequencing can optionally analyze genes not included in the target panel.
Capable of up to 20,000-30,000 cells/analysis, pairing efficiency of mouse and human bio-derived TCRα/β is around 20%-80% (depending on cell activation state).
Simultaneous analysis with protein using BD's Abseq, BioLegend's TotalSeq, etc. is also available
TAS-Seq2 detects about 3 times more genes than BD's WTA kit
TAS-Seq2 has a higher T-cell receptor pairing rate than BD's WTA kit
Example of analysis of tumor-infiltrating CD8⁺T cells in a B16F10 subcutaneously implanted tumor mouse model upon anti-PD-L1 treatment (WTA)
Approx. 50,000 reads/cell
EXPRESSION PATTERNS OF REPRESENTATIVE CD8+ T CELL MARKER GENES
Clusters identified by TAS-Seq2
0: terminally exhausted, 1: effector, 2: proliferated, 3: exhausted progenitor-1, 4: exhausted progenitor-2, 5: naïve-like, 6: stem-like, 7: dying cell
TAS-Seq2 can identify CD8+ T cell subsets that are difficult to identify with BD's WTA kit
TAS-Seq2 can clearly detect genes involved in the regulation of CD8+ T cell function with a lower drop-out rate

From sample receipt
Complete sequence data
Mapping result files, etc.
The official report will be delivered on a hard drive at the time of delivery
A mapping analysis report will be included in the formal report
An example of the report can be seen in the example of the analysis of mouse tumor-infiltrating T cells
Example of analysis of mouse tumor-infiltrating T cells
Tumor-infiltrating T cells (14,100 cells) were classified into 10 clusters and visualized by dimensional compression; clones sharing the TCR were then defined and the properties of each clone were evaluated; data consisted of single cell RNA-seq data and single cell TCR repertoireanalysis data.
The actual report will also be in this style
