NGS Analysis of Hematology-Oncology Clonality Testing
This news was updated in April 2024
Invivoscribe’s NGS LymphoTrack® Dx Assays are used to detect clonal gene rearrangements, somatic hypermutations and for the study of measurable residual disease (MRD). The full clonality suite of LymphoTrack® Dx Assays are CE-marked and developed for use with the leading NGS platforms, including 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 rearrangement, and with the IGHV Leader or IGH FR1 assay, the extent of IGHV somatic hypermutation (SHM).
Key benefits of LymphoTrack® Dx Assays
Common sources of DNA – Formalin-fixed paraffin-embedded (FFPE), fresh/frozen tissue, peripheral blood, bone marrow
One-Step PCR Master Mixes
Multiplexing – Reduces Costs by Combining:
Multiple Samples - up to 12 (Ion S5/PGM™) & 24 (MiSeq®)
Multiple Invivoscribe Assays - up to 72 or 168 Samples
