Background: T cell receptor beta (TCRβ) immune repertoire analysis by next-generation sequencing
is emerging as a valuable tool for research studies of the tumor microenvironment
and potential immune responses to cancer immunotherapy. Here we describe an AmpliSeqTM-based TCRβ sequencing assay that leverages the long read capability of the Ion 530TM chip to provide coverage of all three complimentary determining region (CDR) domains
of the human TCRβ chain. We demonstrate use of the assay to evaluate tumor-infiltrating
T cell repertoire features, monitor manufacture of therapeutic T cells, and discover
TRBV gene allele polymorphisms that may predict autoimmune disease or immune-mediated
adverse events.
