LymphoTrack® Dx Assays

LymphoTrack® Dx Assay kits are designed for the identification of gene rearrangements in hematologic samples utilizing NGS technologies


Invivoscribe’s LymphoTrack® Dx Assays are used to identify and track clonal lymphocyte populations. These CE-IVD assays, developed for use with the leading Next-Generation Sequencing (NGS) platforms, include optimized multiplex PCR master mixes with primers incorporating platform specific adapters and specimen tracking sequencing identification tags for a one-step PCR workflow. A comprehensive bioinformatics software package is provided free of charge with purchase; enabling you to identify the DNA sequence, clonal prevalence, V-J family identity for each gene rearrangements, and with the IGH assays, the extent of IGHV somatic hypermutation (SHM). With this state-of-the-art assay, the gene rearrangement status of several million lymphocytes in blood, bone marrow, or tissue samples can be both identified and characterized.

Key benefits of LymphoTrack® Dx Assays
