Recommended standard materials for immune assays
| Technology/Assay | Recommended Reference Materials |
|---|---|
| Blood-based assays | Cell lines or control PBMC donor samples prepared and cryopreserved following SOP (reference samples) |
| Immunohistochemistry assays | Control cell lines or tissue specimens (e.g., human tonsil for PD-L1 staining) or cell lines processed and embedded in paraffin (not to be used for interpreting patient data) |
| RNA/DNA based assays (NGS, TCR/BCR sequencing, gene expression profiling) | Synthetic mimic libraries, TCR/BCR DNA synthetic templates, synthetic vectors, company or WHO and NIST references |
