Registration for the EQA 2021 is open
Registration for the 2021 External Quality Assessment Scheme for IG/TR Clonality Testing in Suspected Lymphoproliferations/Lymphoma organized by the EuroClonality network in collaboration with the Biomedical Quality Assurance Research Unit of the University of Leuven, is open.
Detailed information on the organization of the QC, registration and result submission can be found on http://www.eqascheme.org/
New EuroClonality publication on 1-tube TRG assays, discontinuation of commercial TRG 2-tube assay
Production and sales of the EuroClonality/BIOMED-2 TRG tube A-B assays has been discontinued by Invivoscribe, as the Invivoscribe TRG2.0 assay (1-tube assay) is available since a couple of years. The performance of the Invivoscribe TRG2.0 assay (full kit with controls: #12070101/12070111) has recently been evaluated in a multi-center study in comparison with the EuroClonality/BIOMED-2 TRG 2-tube assay as well as a new EuroClonality TRG 1-tube assay (Armand et al, HemaSphere 2019;3:e255). The latter was designed with the following specifications: (i) to regroup PCR products within a limited size range, (ii) to generate relatively short PCR products (<200 bp), (iii) to combine all primers within a single tube. Compared to the classical EuroClonality/BIOMED-2 TRG 2-tube assay, both 1-tube assays displayed fairly similar performances and demonstrated easier interpretation as well as a lower risk of false positives from minor peaks in dispersed repertoires. In addition, both assays generate smaller fragments, likely to be better adapted to analysis of formalin-fixed paraffin-embedded tissue samples.
New EuroClonality-NGS publications and SOPs
Three new manuscripts of the EuroClonality-NGS Working Group have been accepted in Leukemia. Two SOPs related to these publications are available in the protocols section of the EuroClonality website: “NGS-based clonality assessment of immunoglobulin gene rearrangements for the Ion Torrent platform” and “Two-step IG/TR NGS-based marker identification for the Illumina MiSeq platform”.
EuroClonality-NGS Consortium on Next-Generation Sequencing for IG / TR immunogenetic analysis
Due to the continuing spreading of the Coronavirus and the status of the travel restrictions in European countries, the 2021 EuroClonality workshop will be cancelled.
The registration procedure for the 2022 EuroClonality workshop will be opened in the summer of 2021.
