Mi Sequence

Why sequence the immune repertoire?

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.

eBook 1: An Intro to Immunology and Immune Sequencing

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

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.

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.
