nCounter® TCR Diversity Panel


Helping Your Research

A diverse population of T cell receptors (TCRs) is a hallmark of a healthy, unchallenged adaptive immune system; however, the usage of TCR variable regions changes upon challenge with a pathogen, cancer, or transplanted organ.  Shifts in TCR diversity can be indicative of disease onset and progression, response/non-response to treatment, and/or disease recovery.  The nCounter TCR Diversity Panel allows you to rapidly determine usage of TCR variable regions and shifts in TCR diversity in response to cancer, infectious disease, autoimmunity, or transplanted organs without any enzymatic steps or sequencing.

How it Works

Directly profile 129 human genes, including T cell receptor variable and constant regions and other T cell markers:

  • CD3/CD4/CD8
  • Naïve & Memory Markers
  • NK Cell Markers

Measure shifts in TCR diversity in response to disease or therapeutic treatments.

Simultaneously measure TCR diversity and T cell phenotype with a streamlined workflow

Obtain a report with a TCR diversity score for each sample.

Customize with up to 55 gene Panel Plus to add additional T cell biology content

TCR Diversity Made Easy

The nCounter TCR Diversity Panel has broad applicability for biomarker development, immune profiling, and cell screening across cancer, infectious disease, autoimmunity, and organ transplant. Profile overnight the abundance of alpha, beta, delta, and gamma variable regions as well as constant regions with minimal hands-on time and receive an automated report with a diversity score for each sample.



Biological Framework

The TCR Diversity Panel contains probes for all alpha, beta, delta, and gamma variable and constant regions as well as important immune cell markers for relevant T cell biology.

TCR Diversity Report

The TCR Diversity report is available for purchase separately from NanoString for use within the ROSALIND® Platform and evaluates the expression of variable regions of the T cell receptor. The variable regions are assessed for overall expression (above or below background) and normalized to a panel standard which allows for more precise quantification of these variable regions. An estimate of TCR Diversity is calculated and shown relative to designated grouping variables.

The TCR score calculates the diversity of T cell receptor beta variable regions within a sample. The score is based on the Shannon Diversity index calculation, a mathematical measure of species diversity within a community. This ecological calculation accounts for the abundance and evenness of the variable regions present within a given sample versus the population of T cell receptors within a given dataset. A given score is relative within a dataset, and a higher TCR score means there is a more diverse population of variable regions or a less clonal population. A lower TCR score means there is less diversity or a more clonal population. True clonality can only be determined by full sequencing of the T cell receptors, but clonality can be estimated by measuring the diversity of TCR beta variable regions.

The ROSALIND® Platform

ROSALIND is a cloud-based platform that enables scientists to analyze and interpret differential gene expression data without the need for bioinformatics or programming skills.  ROSALIND makes analysis of nCounter data easy, with guided modules for:

  • Normalization
  • Quality Control
  • Individual Pathway Analysis
  • Differential Expression
  • Gene Set Analysis

nCounter customers can access ROSALIND free of charge.

Multiple Inflammatory Syndrome in Children (MIS-C) is a delayed and severe complication of SARS-CoV-2 infection that strikes previously healthy children. As MIS-C combines clinical features of Kawasaki disease and Toxic Shock Syndrome (TSS), we aimed to compare the immunological profile of pediatric patients with these different conditions.
