T-cell ELISpot Proficiency Panel

In collaboration with CIC (the US Cancer Immuno-therapy Consortium of the CRI) and CIMT (the European Association for Cancer Immunotherapy), Immudex offers Proficiency Panels as a non-profit service to help researchers and clinicians worldwide evaluate and compare their immune monitoring performance with T-cell ELISpot assays.

Using laboratory-specific protocols, plates, and plate reader, participants determine the number of IFN-γ secreting antigen-specific T cells in provided PBMC samples using ELISpot and receive a report comparing the results from all participating laboratories.

What You Receive

PBMC samples: identical for all participants
Peptide pools: PepMix™ HCMV (pp65) + CEFX Ultra SuperStim Pool
Negative control reagent
Assay instructions

What You Measure

Proficiency Performance 2021

In the ELISpot Proficiency Panel 2021, all laboratories received identical PBMC samples for identification of IFN-γ secreting antigen-specific T-cells, and results were collated to assess the relative accuracy of results across the different laboratories. 13 of the 29 participants (44,8%) had a relative accuracy of between 0.66-1.5 and are considered to be “in the average range” (dark purple columns).
