MHC I Dextramer® – Identify Antigen-Specific CD8+ T Cells
Capture the Complete Diversity of T Cells
MHC I binds and presents antigens from the cell cytosol to activate antigen-specific CD8+ T cells. This antigen-specific immune response is a key process in cancer, autoimmune disease, transplantation, infectious disease, and allergy. Thus, examining the full repertoire of CD8+ T cells, including those with low antigen affinity, is essential.
With an optimized number of MHC-peptide complexes and a choice of fluorophores (PE, APC, FITC, or none), MHC I Dextramer® reagents boost analysis sensitivity in flow cytometry beyond that achieved by other technologies.


MHC I Dextramer® detects low-affinity antigen-specific CD8+ T cells invisible to the corresponding tetramer (Dolton et al. 2014).
No Compromises in Performance
MHC I Dextramer® reagents are designed to meet strict quality and performance criteria, ensuring highly reliable research insights.
- Get the full picture of CD8+ T-cell responses, even the low-affinity ones.
- Ensure consistent, reproducible, and comparable results
- Expand the limits of your research
- Secure flexibility in your experiments
Order MHC I Dextramer®
You can order MHC I Dextramer® reagents in one of three ways:
- Use the table below to find and order your MHC I Dextramer® reagent online
- If you can’t find the reagent to meet your research needs, create a custom reagent using our custom tool at the bottom of the page
- Alternatively, send an e-mail to ordering@immudex.com specifying:
- Catalog number or desired MHC allele-peptide combination:
- Calculate the predicted MHC-peptide affinity using our prediction tool
- Consult our lists of available MHC alleles - Fluorophore (PE, APC, FITC, or none)
- Test size (50,150, 500, 1000 tests). One test is 10 µl reagent and sufficient to stain 1–3 x 106 lymphoid cells or 1–3 x 105 clonal antigen-specific T cells.
Immudex has updated the catalog numbers. To learn more about it, please consult the document here
