Ion Torrent™ Oncomine™ BCR IGH SR Assay, DNA

The Ion Torrent Oncomine BCR IGH SR Assay, DNA, is a robust, targeted next-generation sequencing (NGS) assay designed for use in hematology-oncology and minimal residual disease (MRD) monitoring research. It can also be used to investigate immunotherapy biomarkers, as well as in infectious and autoimmune disease research. The assay kit includes a single pool of multiplex PCR primers, total dNTPs, and library reagents.

The Oncomine BCR IGH SR Assay, DNA, accurately identifies and measures clonal expansion of B lymphocytes using genomic DNA from bone marrow, whole blood, peripheral blood leukocytes (PBLs), peripheral blood mononuclear cells (PBMCs), and fresh-frozen and formalin-fixed paraffin-embedded (FFPE) research samples. Using Ion AmpliSeq technology, the assay identifies unique B-cell clones through targeting of the highly diverse complementarity-determining region 3 (CDR3) of the B-cell receptor (BCR) immunoglobulin heavy (IGH) chain from a DNA template. The nucleotide sequence of the IGH CDR3 region serves as a natural barcode to enable clone identification for MRD clinical research. The measurements of B-cell clonal expansion and diversity are useful for pharmacodynamics and vaccine biomarker research. IGH CDR3-region amino acid motifs may reveal signatures of B-cell responses to defined antigens for use as future markers of autoimmune or infectious disease.
