Immunology basics

Structure of T cell and B cell receptors. T cell receptors are made up of two polypeptide chains that together compose one antigen binding region. B cell receptors are made up of four peptides – two light chains and two heavy chains – that comprise two antigen-binding regions.

B cell and T cell structure and function

Diversity and differentiation in the adaptive immune system

Clonotype: A particular CDR3 sequence. Repertoire: All of the clonotypes within a particular BCR or TCR chain. Adaptome: All of the repertoires for each of the 7 different chains.

The immune repertoire and adaptome

NGS basics

Next-generation sequencing workflow: 1) Extraction 2) Library Prep 3) Sequencing 4) Analysis

NGS overview: from sample to sequencer to results

Simple graphic describing the difference between high and low coverage regions in next generation sequencing: higher coverage equates to more reads

NGS considerations: coverage, read length, multiplexing

T cells attacking cancer cell, why sequence the immune repertoire

Why sequence the immune repertoire?

Clonotype distribution in one person. Long-tailed negative distribution with number of clonotypes on the y-axis and nuber of aliquots on the x-axis. When immune repertoire sequencing, you want to cover this highly variable CDR3 region.

How to perform immune repertoire sequencing

All of iRepertoire’s primer systems for immune repertoire sequencing cover the highly variable CDR3 region

iRepertoire’s primer systems

In the first round of arm-PCR, inside and outside TCR/BCR-specific primers amplify the targets of interest, increasing sensitivity and appending communal primer binding sites
