MHC Multimer Proficiency Testing
Originally developed at the initiative of CIC (the US Cancer Immuno-therapy Consortium of the CRI) and CIMT (the European Association for Cancer Immunotherapy), Immudex offers Proficiency Testing as a non-profit service to help researchers and clinicians worldwide evaluate and benchmark their immune monitoring performance with MHC Multimers.
Using laboratory-specific protocols, antibodies, and flow cytometry, participants determine the number of antigen-specific T cells in provided PBMC samples using MHC multimers and receive a report comparing the results from all participating laboratories.
What You Receive
Quality controlled PBMC samples – identical for all participants
If requested, MHC Dextramer® reagents free of charge
Assay instructions
What You Measure
Total number of CD8+ T cells in samples
Number of antigen specific CD8+ T cells in samples, stained with MHC Multimers
In addition, as a special feature this year, we offer participants the option of enumerating MAIT cells with our new MR1 Dextramer®

Proficiency Performance 2020
In the MHC Multimer Proficiency Panel 2020, all laboratories received identical PBMC samples for identification of antigen-specific T-cells using MHC multimers, and results were collated to assess the relative accuracy of results across the different laboratories. 13 out of 19 participants (68,4%) had a relative accuracy between 0.66 – 1.5 and were considered to be in “the average range” (dark blue columns).
