Immunoprofiling

Immunoprofiling sample preparation

DNA sequencing-based immunoprofiling quantitatively measures AR diversity in samples by determining the sequences of V(D)J junctions. AR receptor diversity is vast due to a combinatorial rearrangement process that inserts a variable number of random DNA bases at each junction. In the sequencing process V(D)J junctions are amplified with V and J gene specific primers and, to be quantitative, differences in amplification rates that are due to primer sequences must be factored into each assay.

Immunoprofiling steps of the general workflow

Immunoprofiling is the quantitative measurement of antigen receptors (ARs; antibodies or T-cell receptors) in a sample and is a hot area in biotechnology. Immunoprofiling is used to assess the diversity of antigen receptors (ARs: antibodies and T-Cell receptors) and how this diversity changes in response to allergens, infections, or vaccines. In cancer therapy, Immunoprofiling is used to develop biomarkers and understand how an individual’s immune cells fight tumors, and predict individuals' response to immunotherapy.
