  • Service Description

    BGI’s Immune Repertoire Sequencing (IR-SEQ) service enables partners to examine the adaptive immune system with bias-controlled multiplex PCR or 5’ RACE amplification and high-throughput sequencing of T-cell and B-cell receptors. 
IR-Seq allows researchers to better understand adaptive immune-mediated diseases and supports research in to a broad range of other applications including:

    • Biomarker discovery
    • Infectious diseases
    • Vaccine development and efficacy
    • Asthma and allergy
    • Transplant rejection and tolerance
    • Immune response to malignancy
    • Autoimmune diseases
    • Cancer immunotherapy
  • Sequencing Service Specification

    Services are performed on the HiSeq4000 platform, PE100/150 for mul-PCR library

    Miseq platform: PE300 for 5’RACE library

    Mul-PCR: short insert library

    5’RACE: long insert library
